26th century BC Sumerian document
Sumerian (𒅴𒂠 EME.G̃IR15 "native tongue") is the language of ancient Sumer and a language isolate that was spoken in southern Mesopotamia (modern-day Iraq). During the 3rd millennium BC, an intimate cultural symbiosis developed between the Sumerians and the Akkadians, which included widespread bilingualism. The influence of Sumerian on the East Semitic language Akkadian (and vice versa) is evident in all areas, from lexical borrowing on a substantial scale, to syntactic, morphological, and phonological convergence. This has prompted scholars to refer to Sumerian and Akkadian in the third millennium BC as a Sprachbund.
Akkadian gradually replaced Sumerian as a spoken language around 2000 BC (the exact dating being subject to debate), but Sumerian continued to be used as a sacred, ceremonial, literary and scientific language in Mesopotamia until the 1st century AD. Thereafter it was likely forgotten until the 19th century, when Assyriologists began deciphering the cuneiform inscriptions and excavated tablets left by these speakers.

The history of written Sumerian can be divided into several periods:
- Archaic Sumerian – 31st–26th century BC
- Old or Classical Sumerian – 26th–23rd century BC
- Neo-Sumerian – 23rd–21st century BC
- Late Sumerian – 20th–18th century BC
- Post-Sumerian – after 1700 BC
Archaic Sumerian is the earliest stage of inscriptions with linguistic content, beginning with the Jemdet Nasr (Uruk III) period from about the 31st to 30th centuries BC. It succeeds the proto-literate period, which spans roughly the 35th to 30th centuries.
Some versions of the chronology may omit the Late Sumerian phase and regard all texts written after 2000 BC as Post-Sumerian. The term "Post-Sumerian" is meant to refer to the time when the language was already extinct and only preserved by Babylonians and Assyrians as a liturgical and classical language (for religious, artistic and scholarly purposes). The extinction has traditionally been dated approximately to the end of the Third Dynasty of Ur, the last predominantly Sumerian state in Mesopotamia, about 2000 BC. However, this date is very approximate, as many scholars have contended that Sumerian was already dead or dying as early as around 2100 BC, by the beginning of the Ur III period, while others believe that Sumerian persisted as a spoken language in a small part of Southern Mesopotamia (Nippur and its surroundings) until as late as 1700 BC. Whatever the status of spoken Sumerian between 2000 and 1700 BC, it is from this period that a particularly large quantity of literary texts and bilingual Sumerian-Akkadian lexical lists survive, especially from the scribal school of Nippur. This, along with the particularly intensive official and literary use of the language in Akkadian-speaking states during the same time, is the basis for the distinction between a Late Sumerian period and all subsequent time.
The standard variety of Sumerian is called eme-ĝir. A notable variety or sociolect is called eme-sal (𒅴𒊩 EME.SAL). Eme-sal is used exclusively by female characters in some literary texts (this may be compared to the female languages or language varieties that exist or have existed in some cultures, e.g. among the Chukchis and the Island Caribs). In addition, it is dominant in certain genres of cult songs. The special features of eme-sal are mostly phonological (e.g. m is often used instead of ĝ (i.e. [ŋ]) as in me vs standard ĝe26, "I"), but words different from the standard language are also used (e.g. ga-ša-an vs standard nin, "lady").
Sumerian is an agglutinative, split ergative, and subject-object-verb language. It behaves as a nominative–accusative language in the 1st and 2nd persons of the incomplete tense-aspect, but as ergative–absolutive in most other forms of the indicative mood.
Sumerian nouns distinguish two classes of animacy: animate and inanimate. Animate nouns include humans, gods, and in some instances the word for "statue". It does not display gender. Suffixes mark a noun's case: absolutive(-Ø), ergative(-e), dative/allative(-r(a) animate, -e inanimate, "to, for"), genitive(-(a)k "of"), locative(-a, only inanimate, "in, at"), comitative(-da "with"), equative(-gin "as, like"), directive/adverbial(-š(e) "toward"), ablative(-ta, only inanimate, "from"). The naming and number of cases vary according to differing analyses of Sumerian linguistics. Noun phrases are right branching with adjectives and modifiers following nouns.
Sumerian verbs have a tense-aspect complex, contrasting complete and incomplete actions/states. The two have different conjugations and many have different roots. Verbs also mark mood, voice, polarity, iterativity, and intensity; and agree with subjects and objects in number, person, animacy, and case. Sumerian moods are: indicative, imperative, cohortative, precative/affirmative, prospective aspect/cohortative mood, affirmative/negative-volitive, unrealised-volitive?, negative?, affirmative?, polarative, and are marked by a verbal prefix. The prefixes appear to conflate mood, aspect, and polarity; and their meaning is also affected by the tense-aspect complex. Sumerian voices are: active, and middle or passive. Verbs are marked for three persons: 1st, 2nd, 3rd; in two numbers: singular and plural. Finite verbs have three classes of prefixes: modal prefixes, conjugational prefixes, and pronominal/dimensional prefixes. Modal prefixes confer the above moods on the verb. Conjugational prefixes are thought to confer perhaps venitive/andative, being/action, focus, valency, or voice distinctions on the verb. Pronominal/dimensional prefixes correspond to noun phrases and their case. Non-finite verbs include participles and relative clause verbs, both formed through nominalisation. Finite verbs take prefixes and suffixes, non-finite verbs only take suffixes. Verbal roots are mostly monosyllabic, though verbal root duplication and suppletion can also occur to indicate plurality. Root duplication can also indicate iterativity or intensity of the verb.
Sumerian is a language isolate. Ever since decipherment, it has been the subject of much effort to relate it to a wide variety of languages. Because it has a peculiar prestige as the most ancient written language, proposals for linguistic affinity sometimes have a nationalistic background. Such proposals enjoy virtually no support amongst linguists because of their unverifiability. Sumerian was at one time widely held to be an Indo-European language, but that view later came to be almost universally rejected.
A few examples of proposed linguistic affiliations include:
- Kartvelian languages (Nicholas Marr)
- Munda languages (Igor M. Diakonoff)
- Dravidian languages (see Elamo-Dravidian)
- Uralic languages (Simo Parpola) or, more generally, Ural–Altaic languages (Simo Parpola, C. G. Gostony, András Zakar, Ida Bobula)
- Basque language (Aleksi Sahala)
- Nostratic languages (Allan Bomhard)
- Sino-Tibetan languages (Jan Braun, following C. J. Ball, V. Christian, and K. Bouda), close to Tibeto-Burman languages, or, more generally, Dené–Caucasian languages (John Bengtson)
It has also been suggested that the Sumerian language descended from a late Paleolithic creole language (Høyrup 1992). However, no conclusive evidence, only some typological features, can be found to support Høyrup's view.
A more widespread hypothesis posits a Proto-Euphratean language that preceded Sumerian in Southern Mesopotamia and exerted an areal influence on it, especially in the form of polysyllabic words that appear "un-Sumerian"–making them suspect of being loanwords–and are not traceable to any other known language. There is little speculation as to the affinities of this substratum language, or these languages, and it is thus best treated as unclassified. Researchers such as Gonzalo Rubio disagree with the assumption of a single substratum language and argue that several languages are involved. A related proposal by Gordon Whittaker is that the language of the proto-literary texts from the Late Uruk period (c. 3350–3100 BC) is really an early Indo-European language which he terms "Euphratic".
The Sumerian language is one of the earliest known written languages. The "proto-literate" period of Sumerian writing spans c. 3300 to 3000 BC. In this period, records are purely logographic, with no linguistic or phonological content. The oldest document of the proto-literate period is the Kish tablet. Falkenstein (1936) lists 939 signs used in the proto-literate period (late Uruk, 34th to 31st centuries).
Records with unambiguously linguistic content, identifiably Sumerian, are those found at Jemdet Nasr, dating to the 31st or 30th century BC. From about 2600 BC, the logographic symbols were generalized using a wedge-shaped stylus to impress the shapes into wet clay. This archaic cuneiform ("wedge-shaped") mode of writing co-existed with the pre-cuneiform archaic mode. Deimel (1922) lists 870 signs used in the Early Dynastic IIIa period (26th century). In the same period the large set of logographic signs had been simplified into a logosyllabic script comprising several hundred signs. Rosengarten (1967) lists 468 signs used in Sumerian (pre-Sargonian) Lagash. The pre-Sargonian period of the 26th to 24th centuries BC is the "Classical Sumerian" stage of the language.
The cuneiform script is adapted to Akkadian writing from the mid third millennium. Our knowledge of Sumerian is based on Akkadian glossaries. During the "Sumerian Renaissance" (Ur III) of the 21st century BC, Sumerian is written in already highly abstract cuneiform glyphs directly succeeded by Old Assyrian cuneiform.
Transcription, in the context of cuneiform, is the process in which an epigraphist makes a line art drawing to show the signs on a clay tablet or stone inscription in a graphic form suitable for modern publication. Not all epigraphists are equally reliable, and before a scholar publishes an important treatment of a text, the scholar will often arrange to collate the published transcription against the actual tablet, to see if any signs, especially broken or damaged signs, should be represented differently.
Transliteration is the process in which a Sumerologist decides how to represent the cuneiform signs in Roman script. Depending on the context, a cuneiform sign can be read either as one of several possible logograms, each of which corresponds to a word in the Sumerian spoken language, as a phonetic syllable (V, VC, CV, or CVC), or as a determinative (a marker of semantic category, such as occupation or place). (See the article Transliterating cuneiform languages.) Some Sumerian logograms were written with multiple cuneiform signs. These logograms are called diri-spellings, after the logogram 'diri' which is written with the signs SI and A. The text transliteration of a tablet will show just the logogram, such as the word 'diri', not the separate component signs.
The key to reading logosyllabic cuneiform came from the Behistun inscription, a trilingual cuneiform inscription written in Old Persian, Elamite and Akkadian. (In a similar manner, the key to understanding Egyptian hieroglyphs was the bilingual Rosetta stone and Jean-François Champollion's transcription in 1822.)
In 1838 Henry Rawlinson, building on the 1802 work of Georg Friedrich Grotefend, was able to decipher the Old Persian section of the Behistun inscriptions, using his knowledge of modern Persian. When he recovered the rest of the text in 1843, he and others were gradually able to translate the Elamite and Akkadian sections of it, starting with the 37 signs he had deciphered for the Old Persian. Meanwhile, many more cuneiform texts were coming to light from archaeological excavations, mostly in the Semitic Akkadian language, which were duly deciphered.
By 1850, however, Edward Hincks came to suspect a non-Semitic origin for cuneiform. Semitic languages are structured according to consonantal forms, whereas cuneiform, when functioning phonetically, was a syllabary, binding consonants to particular vowels. Furthermore, no Semitic words could be found to explain the syllabic values given to particular signs. Julius Oppert suggested that a non-Semitic language had preceded Akkadian in Mesopotamia, and that speakers of this language had developed the cuneiform script.
In 1856, Hincks argued that the untranslated language was agglutinative in character. The language was called "Scythic" by some, and, confusingly, "Akkadian" by others. In 1869, Oppert proposed the name "Sumerian", based on the known title "King of Sumer and Akkad", reasoning that if Akkad signified the Semitic portion of the kingdom, Sumer might describe the non-Semitic annex.
Ernest de Sarzec began excavating the Sumerian site of Tello (ancient Girsu, capital of the state of Lagash) in 1877, and published the first part of Découvertes en Chaldée with transcriptions of Sumerian tablets in 1884. The University of Pennsylvania began excavating Sumerian Nippur in 1888.
A Classified List of Sumerian Ideographs by R. Brünnow appeared in 1889.
The bewildering number and variety of phonetic values that signs could have in Sumerian led to an unfortunate detour in understanding the language – a Paris-based orientalist, Joseph Halévy, argued from 1874 onward that Sumerian was not a natural language, but rather a secret code (a cryptolect), and for over a decade the leading Assyriologists battled over this issue. For a dozen years, starting in 1885, even the great Friedrich Delitzsch accepted Halévy's arguments, not renouncing Halévy until 1897.
François Thureau-Dangin working at the Louvre in Paris also made significant contributions to deciphering Sumerian with publications from 1898 to 1938, such as his 1905 publication of Les inscriptions de Sumer et d’Akkad. Charles Fossey at the Collège de France in Paris was another prolific and reliable scholar. His pioneering Contribution au Dictionnaire sumérien–assyrien, Paris 1905–1907, turns out to provide the foundation for P. Anton Deimel's 1934 Sumerisch-Akkadisches Glossar (vol. III of Deimel's 4-volume Sumerisches Lexikon).
In 1908, Stephen Herbert Langdon summarized the rapid expansion in knowledge of Sumerian and Akkadian vocabulary in the pages of Babyloniaca, a journal edited by Charles Virolleaud, in an article 'Sumerian-Assyrian Vocabularies', which reviewed a valuable new book on rare logograms by Bruno Meissner. Subsequent scholars have found Langdon's work, including his tablet transcriptions, to be not entirely reliable.
Friedrich Delitzsch published a learned Sumerian dictionary and grammar in the form of his Sumerisches Glossar and Grundzüge der sumerischen Grammatik, both appearing in 1914. Delitzsch's student, Arno Poebel, published a grammar with the same title, Grundzüge der sumerischen Grammatik, in 1923, and for 50 years it would be the standard for students studying Sumerian. Poebel's grammar was finally superseded in 1984 on the publication of The Sumerian Language, An Introduction to its History and Grammatical Structure, by Marie-Louise Thomsen. While much of Thomsen's understanding of Sumerian grammar would now be rejected by most or all Sumerologists, Thomsen's grammar (often with express mention of the critiques put forward by Pascal Attinger in his 1993 Eléments de linguistique sumérienne: La construction de du11/e/di «dire») is the starting point of most recent academic discussions of Sumerian grammar.
More recent monograph-length grammars of Sumerian include Dietz Otto Edzard's 2003 Sumerian Grammar and Bram Jagersma's 2010 A Descriptive Grammar of Sumerian (currently digital, but soon to be printed in revised form by Oxford University Press). Piotr Michalowski's essay (entitled, simply, "Sumerian") in the 2004 The Cambridge Encyclopedia of the World's Ancient Languages has also been recognized as a good modern grammatical sketch.
There is relatively little consensus, even among reasonable Sumerologists, in comparison to the state of most modern or classical languages. Verbal morphology in particular is hotly disputed. In addition to the general grammars, there are many monographs and articles about particular areas of Sumerian grammar, without which a survey of the field could not be considered complete.
The primary institutional lexical effort in Sumerian is the Pennsylvania Sumerian Dictionary project, begun in 1974. In 2004, the PSD was released on the Web as the ePSD. The project is currently supervised by Steve Tinney. It has not been updated on-line since 2006, but Tinney and colleagues are working on a new edition of the ePSD, a working draft of which is available on-line.
Phonology and grammar
Typologically, as mentioned above, Sumerian is classified as an agglutinative split ergative language. Ever since its decipherment, the research of Sumerian has been made difficult not only by the lack of any native speakers, but also by the relative sparseness of linguistic data, the apparent lack of a closely related language, and the features of the writing system.
Assumed phonological or morphological forms will be between slashes //, with plain text used for the standard Assyriological transcription of Sumerian. Most of the following examples are unattested.
Modern knowledge of Sumerian phonology is certainly very flawed and incomplete because of the lack of native speakers, the transmission through the filter of Akkadian phonology and the difficulties posed by the cuneiform script. As I.M. Diakonoff observes, "when we try to find out the morphophonological structure of the Sumerian language, we must constantly bear in mind that we are not dealing with a language directly but are reconstructing it from a very imperfect mnemonic writing system which had not been basically aimed at the rendering of morphophonemics."
Sumerian is conjectured to have at least the following consonants:
|Plosive||plain||p ⟨b⟩||t ⟨d⟩||k ⟨g⟩|
|aspirated||pʰ ⟨p⟩||tʰ ⟨t⟩||kʰ ⟨k⟩|
|Fricative||s||ʃ ⟨š⟩||x ⟨ḫ⟩|
- a simple distribution of six stop consonants, in three places of articulation distinguished by aspiration, though later stages may have featured voicing:
As a rule, /p/, /t/ and /k/ did not occur word-finally.
- a phoneme usually represented by /ř/ (sometimes written dr) that was probably a voiceless aspirated alveolar affricate. This phoneme later became /d/ or /r/ in northern and southern dialects, respectively.
- a simple distribution of three nasal consonants in similar distribution to the stops:
- a set of three sibilants:
- s, likely a voiceless alveolar fricative),
- z, likely a voiceless unaspirated alveolar affricate, /t͡s/, as shown by Akkadian loans from /s/=[t͡s] to Sumerian /z/. In early Sumerian, this would have been the unaspirated counterpart to /ř/.
- š (generally described as a voiceless postalveolar fricative, /ʃ/, as in ship),
- a velar fricative /ḫ/ (sometimes written h).
- two liquid consonants:
The existence of various other consonants has been hypothesized based on graphic alternations and loans, though none have found wide acceptance. For example, Diakonoff lists evidence for two l-sounds, two r-sounds, two h-sounds, and two g-sounds (excluding the velar nasal), and assumes a phonemic difference between consonants that are dropped word-finally (such as the g in zag > za3) and consonants that remain (such as the g in lag). Other "hidden" consonant phonemes that have been suggested include semivowels such as /j/ and /w/, and a glottal fricative /h/ or a glottal stop that could explain the absence of vowel contraction in some words—though objections have been raised against that as well.
Very often, a word-final consonant was not expressed in writing – and was possibly omitted in pronunciation – so it surfaced only when followed by a vowel: for example the /k/ of the genitive case ending -ak does not appear in e2 lugal-la "the king's house", but it becomes obvious in e2 lugal-la-kam "(it) is the king's house" (compare liaison in French).
The vowels that are clearly distinguished by the cuneiform script are /a/, /e/, /i/, and /u/. It has also been argued that an /o/ phoneme might have existed but was concealed by the Akkadian transliteration, which does not distinguish it from /u/. However, that hypothesis has not found wide support.
There is some evidence for vowel harmony according to vowel height or advanced tongue root in the prefix i3/e- in inscriptions from pre-Sargonic Lagash (the specifics of the pattern have led a handful of scholars to postulate not only an /o/ phoneme, but even an /ɛ/ and, most recently, an /ɔ/) Many cases of partial or complete assimilation of the vowel of certain prefixes and suffixes to one in the adjacent syllable are reflected in writing in some of the later periods, and there is a noticeable though not absolute tendency for disyllabic stems to have the same vowel in both syllables. What appears to be vowel contraction in hiatus (*/aa/, */ia/, */ua/ > a, */ae/ > a, */ue/ > u, etc.) is also very common.
Syllables could have any of the following structures: V, CV, VC, CVC. More complex syllables, if Sumerian had them, are not expressed as such by the cuneiform script.
The Sumerian noun is typically a one or two syllable root (igi "eye", e2 "house, household", nin "lady"), although there are also some roots with three syllables like šakanka "market". There are two grammatical genders, usually called human and non-human (the first includes gods and the word for "statue" in some instances, but not plants or animals, the latter also includes collective plural nouns), whose assignment is semantically predictable.
The adjectives and other modifiers follow the noun (lugal maḫ "great king"). The noun itself is not inflected; rather, grammatical markers attach to the noun phrase as a whole, in a certain order. Typically, that order would be noun – adjective – numeral – genitive phrase – relative clause – possessive marker – plural marker – case marker, for example /diĝir gal-gal-ĝu-ne-ra/ ("god great (reduplicated)-my-plural-dative" = "for all my great gods"). The possessive, plural and case markers are traditionally referred to as "suffixes", but have recently also been described as enclitics or postpositions.
The plural markers are /-(e)ne/ (optional) for nouns of the human gender. Non-human nouns are not marked by a plural suffix. However, plurality can also be expressed with the adjective ḫi-a "various", with the plural of the copula /-meš/, by reduplication of the noun (kur-kur "all foreign lands") or of the following adjective (a gal-gal "all the great waters") (reduplication is believed to signify totality) or by the plurality of only the verb form. Plural reference in the verb form occurs only for human nouns. The case markers are /-Ø/ (absolutive), /-e/ (ergative), /-e/ (allative = "to"), /-ak/ (genitive), /-gin/ (equative = "as, like"), /-r(a)/ (dative = "to, for" = indirect object), /-(e)š(e)/ (traditionally called terminative case, but means "towards"), /-da/ (comitative = "together with"), /-a/ (locative = "in, at"), /-ta/ (ablative = "from, by"). Additional spatial or temporal meanings can be expressed by genitive phrases like "at the head of" = "above", "at the face of" = "in front of", "at the outer side of" = "because of" etc.: bar udu ḫad2-ak-a = "outer.side sheep white-genitive-locative" = "in the outer side of a white sheep" = "because of a white sheep".
The attested independent personal pronouns are written ĝe26-e (1st p. sing.), ze2-e (2nd p. sing.), a-ne or e-ne (3rd p. sing. human), and a/e-ne-ne (3rd p. pl. human). The possessive pronominal morphemes are written -ĝu10 (1st p. sing.), -zu (2nd p. sing.), -(a)-n(i) (3rd p. sing. human), -b(i) (3rd p. sing./pl. non-human, also demonstrative and collective), -me (1st pers. pl.), -zu-ne-ne (2nd p. pl.), and -(a)-ne-ne (3rd pers.pl. animate). For most of the suffixes, vowels are subject to loss if they are attached to vowel-final words.
The embedded structure of the noun phrase can be illustrated with the phrase sipad udu siki-ak-ak-ene ("the shepherds of woolly sheep"), where the first genitive morpheme (-a(k)) subordinates siki "wool" to udu "sheep", and the second subordinates udu siki-a(k) "sheep of wool" (or "woolly sheep") to sipad "shepherd".
The Sumerian finite verb distinguishes a number of moods and agrees (more or less consistently) with the subject and the object in person, number and gender. The verb chain may also incorporate pronominal references to the verb's other modifiers, which has also traditionally been described as "agreement", although, in fact, such a reference and the presence of an actual modifier in the clause need not co-occur: not only e2-še3 ib2-ši-du-un "I'm going to the house", but also e2-še3 i3-du-un "I'm going to the house" and simply ib2-ši-du-un "I'm going to it" are possible.
The Sumerian verb also makes a binary distinction according to a category that some regard as tense (past vs present-future), others as aspect (perfective vs imperfective), and that will be designated as TA (tense/aspect) in the following. The two members of the opposition entail different conjugation patterns and, at least for many verbs, different stems; they are theory-neutrally referred to with the Akkadian grammatical terms for the two respective forms – ḫamṭu (quick) and marû (slow, fat). Finally, opinions differ on whether the verb has a passive or a middle voice and how it is expressed.
The verbal root is almost always a monosyllable and, together with various affixes, forms a so-called verbal chain which is described as a sequence of about 15 slots, though the precise models differ. The finite verb has both prefixes and suffixes, while the non-finite verb may only have suffixes. Broadly, the prefixes have been divided in three groups that occur in the following order: modal prefixes, "conjugation prefixes", and pronominal and dimensional prefixes. The suffixes are a future or imperfective marker /-ed-/, pronominal suffixes, and an /-a/ ending that nominalizes the whole verb chain.
The modal prefixes are :
- /Ø-/ (indicative),
- /nu-/ and /la-/, /li-/ (negative; /la/ and /li/ are used before the conjugation prefixes ba- and bi2-),
- /ga-/ (cohortative, "let me/us"),
- /ḫa-/ or /ḫe-/ with further assimilation of the vowel in later periods (precative or affirmative),
- /u-/ (prospective "after/when/if", also used as a mild imperative),
- /na-/ (negative or affirmative),
- /bara-/ (negative or vetitive),
- /nuš-/ (unrealizable wish?) and
- /ša-/ with further assimilation of the vowel in later periods (affirmative?).
Their meaning can depend on the TA.
The meaning, structure, identity and even the number of "conjugation prefixes" have always been a subject of disagreements. The term "conjugation prefix" simply alludes to the fact that a finite verb in the indicative mood must always contain one of them. Some of their most frequent expressions in writing are mu-, i3- (ED Lagash variant: e-), ba-, bi2- (ED Lagash: bi- or be2), im-, im-ma- (ED Lagash e-ma-), im-mi- (ED Lagash i3-mi or e-me-), mi-(always followed by pronominal-dimensional -ni-) and al-, and to a lesser extent a-, am3-, am3-ma-, and am3-mi-; virtually all analyses attempt to describe many of the above as combinations or allomorphs of each other. The starting point of most analyses are the obvious facts that the 1st person dative always requires mu-, and that the verb in a "passive" clause without an overt agent tends to have ba-. Proposed explanations usually revolve around the subtleties of spatial grammar, information structure (focus), verb valency, and, most recently, voice. Mu-, im- and am3- have been described as ventive morphemes, while ba- and bi2- are sometimes analyzed as actually belonging to the pronominal-dimensional group (inanimate pronominal /-b-/ + dative /-a-/ or directive /-i-/). Im-ma-, im-mi-, am3-ma- and am3-mi- are then considered by some as a combination of the ventive and /ba-/, /bi-/ or otherwise a variety of the ventive i3- has been argued to be a mere prothetic vowel, al- a stative prefix, ba- a middle voice prefix, etcetera.
Pronominal and dimensional prefixes
The dimensional prefixes of the verb chain basically correspond to, and often repeat, the case markers of the noun phrase. Like the latter, they are attached to a "head" – a pronominal prefix. The other place where a pronominal prefix can be placed is immediately before the stem, where it can have a different allomorph and expresses the absolutive or the ergative participant (the transitive subject, the intransitive subject or the direct object), depending on the TA and other factors, as explained below. However, this neat system is obscured by the tendency to drop or merge many of the prefixes in writing and possibly in pronunciation as well. -da-, -ta-, -ši- (early -še3-), occurring in this order, are the comitative, ablative and terminative verbal prefixes; the dative (occurring before the others) is probably /-a-/, and a directive /-i-/ (occurring after the others) is widely recognized as well. The pronominal prefixes are /-n-/ and /-b-/ for the 3rd person singular animate and inanimate respectively; the 2nd person singular appears as -e- in most contexts, but as /-r-/ before the dative (-ra-), leading some to assume a phonetic /-ir-/ or /-jr-/. The 1st person may appear as -e-, too, but is more commonly not expressed at all (the same may frequently apply to 3rd and 2nd persons); it is, however, cued by the choice of mu- as conjugation prefix (/mu-/ + /-a-/ → ma-). The 1st, 2nd and 3rd plural infixes are -me-,-re?- and -ne- in the dative and perhaps in other contexts as well, though not in the pre-stem position (see below). An additional exception from the system is the prefix -ni- which corresponds to a noun phrase in the locative – in which case it doesn't seem to be preceded by a pronominal prefix – and, according to Gábor Zólyomi and others, to an animate one in the directive – in the latter case it is analyzed as pronominal /-n-/ + directive /-i-/. Zólyomi and others also believe that special meanings can be expressed by combinations of non-identical noun case and verb prefix. Also according to some researchers /-ni-/ and /bi-/ acquire the forms /-n-/ and /-b-/ (coinciding with the absolutive–ergative pronominal prefixes) before the stem if there isn't already an absolutive–ergative pronominal prefix in pre-stem position: mu-un-kur9 = /mu-ni-kur/ "he went in there" (as opposed to mu-ni-kur9 = mu-ni-in-kur9 = /mu-ni-n-kur/ "he brought in – caused [something or someone] to go in – there".
Pronominal suffixes and conjugation
The pronominal suffixes are /-en/ for the first- and second-person singular, /-e/ for the third singular in marû TA and /-Ø/ in ḫamṭu TA, /-enden/ for the first plural, /-enzen/ for the second plural, /-ene/ for the third plural in marû and /-eš/ in ḫamṭu (the initial vowel in all of the above suffixes can be assimilated to the root). The general principle for pronominal agreement in conjugation is that in ḫamṭu TA, the transitive subject is expressed by the prefix, and the direct object by the suffix, and in the marû TA it is the other way round; as for the intransitive subject, it is expressed, in both TAs, by the suffixes and is thus treated like the object in ḫamṭu and like the subject in marû (except that its third person is expressed, not only in ḫamṭu but also in marû, by the suffixes used for the object in the ḫamṭu TA). A major exception from this generalization are the plural forms – in them, not only the prefix (as in the singular), but also the suffix expresses the transitive subject. Additionally, the prefixes of the plural are identical to those of the singular – /-?-/ or /-e-/, /-e-/, /-n-/, /-b-/ – as opposed to the -me-, -re-?, -ne- that are presumed for non-pre-stem position – and some scholars believe that the prefixes of the 1st and second person are /-en-/ rather than /-e-/ when they stand for the object. Before the pronominal suffixes, a suffix /-e(d)-/ with a future or related modal meaning can be inserted, accounting for occurrences of -e in the third-person singular marû of intransitive forms; because of its meaning, it can also be said to signal marû in these forms.
Examples for TA and pronominal agreement: (ḫamṭu is rendered with past tense, marû with present): /i-gub-en/ ("I stood" or "I stand"), /i-n-gub-en/ ("he placed me" or "I place him"); /i-sug-enden/ ("we stood/stand"); /i-n-dim-enden/ ("he created us" or "we create him"); /mu-e?-dim-enden/ ("we created [someone or something]"); i3-gub-be2 = /i-gub-ed/ ("he will/must stand"); ib2-gub-be2 = /i-b-gub-e/ ("he places it"); /i-b-dim-ene/ ("they create it"), /i-n-dim-eš/ ("they created [someone or something]" or "he created them"), /i-sug-eš/ ("they stood" or "they stand").
Confusingly, the subject and object prefixes (/-n-/, /-b-/, /-e-/) are not commonly spelled out in early texts, although the "full" spellings do become more usual during the Third Dynasty of Ur (in the Neo-Sumerian period) and especially during the Late Sumerian period. Thus, in earlier texts, one finds mu-ak and i3-ak (e-ak in early dynastic Lagash) instead of mu-un-ak and in-ak for /mu-n-ak/ and /i-n-ak/ "he/she made", and also mu-ak instead of mu-e-ak "you made". Similarly, pre-Ur III texts also spell the first- and second-person suffix /-en/ as -e, making it coincide with the third person in the marû form.
The verbal stem itself can also express grammatical distinctions. The plurality of the absolutive participant can be expressed by complete reduplication of the stem or by a suppletive stem. Reduplication can also express "plurality of the action itself", intensity or iterativity. With respect to TA marking, verbs are divided in 4 types; ḫamṭu is always the unmarked TA. The stems of the 1st type, regular verbs, do not express TA at all according to most scholars, or, according to M. Yoshikawa and others, express marû TA by adding an (assimilating) /-e-/ as in gub-be2 or gub-bu vs gub (which is, however, nowhere distinguishable from the first vowel of the pronominal suffixes except for intransitive marû 3rd person singular). The 2nd type express marû by partial reduplication of the stem as kur9 vs ku4-ku4; the 3rd type express marû by adding a consonant (te vs teĝ3); and the 4th type use a suppletive stem (dug4 vs e). Thus, as many as four different suppletive stems can exist, as in the admittedly extreme case of the verb "to go": ĝen ("to go", ḫamṭu sing.), du (marû sing.), (e-)re7 (ḫamṭu plur.), sub2 (marû plur.)
The nominalizing suffix /-a/ converts non-finite and finite verbs into participles and relative clauses: sum-ma "given", mu-na-an-sum-ma "which he gave to him", "who gave (something) to him", etc.. Adding /-a/ after the future/modal suffix /-ed/ produces a form with a meaning similar to the Latin gerundive: sum-mu-da = "which will/should be given". On the other hand, adding a (locative-terminative?) /-e/ after the /-ed/ yields a form with a meaning similar to the Latin ad + gerund (acc.) construction: sum-mu-de3 = "(in order) to give".
The copula verb /me/ "to be" is mostly used as an enclitic: -men, -men, -am, -menden, -menzen, -(a)meš.
The imperative mood construction is produced with a singular ḫamṭu stem, but using the marû agreement pattern, by turning all prefixes into suffixes: mu-na-an-sum "he gave (something) to him", mu-na-e-sum-mu-un-ze2-en "you (plur.) gave (something) to him" – sum-mu-na-ab "give it to him!", sum-mu-na-ab-ze2-en "give (plur.) it to him!" Compare the French tu le lui donnes, vous le lui donnez (present tense) – donne-le-lui!, donnez-le-lui!
The basic word order is subject–object–verb; verb finality is only violated in rare instances, in poetry. The moving of a constituent towards the beginning of the phrase may be a way to highlight it, as may the addition of the copula to it. The so-called anticipatory genitive (e2-a lugal-bi "the owner of the house/temple", lit. "of the house, its owner") is common and may signal the possessor's topicality. There are various ways to express subordination, some of which have already been hinted at; they include the nominalization of a verb, which can then be followed by case morphemes and possessive pronouns (kur9-ra-ni "when he entered") and included in "prepositional" constructions (eĝer a-ma-ru ba-ur3-ra-ta "back – flood – conjugation prefix – sweep over – nominalizing suffix – [genitive suffix?] – ablative suffix" = "from the back of the Flood's sweeping-over" = "after the Flood had swept over"). Subordinating conjunctions such as ud-da "when, if", tukum-bi "if" are also used, though the coordinating conjunction u3 "and", a Semitic adoption, is rarely used. A specific problem of Sumerian syntax is posed by the numerous so-called compound verbs, which usually involve a noun immediately before the verb, forming a lexical or idiomatic unit (e.g. šu...ti, lit. "hand-approach" = "receive"; igi...du8, lit. "eye-open" = "see"). Some of them are claimed to have a special agreement pattern that they share with causative constructions: their logical object, like the causee, receives, in the verb, the directive infix, but in the noun, the dative suffix if animate and the directive if inanimate.
