This glossary gives a general overview of the various sound laws that have been formulated by linguists for the various Indo-European languages. A concise description is given for each rule; more details are given in their respective articles.

Proto-Indo-European or in multiple branches

asno law
The word-medial sequence *-mn- is simplified after long vowels and diphthongs or after a short vowel if the sequence was tautosyllabic and preceded by a consonant. The *n was deleted if the vocalic sequence following the cluster was accented, as in Ancient Greek θερμός thermós 'warm' (from Proto-Indo-European *gʷʰermnós 'warm'); otherwise, the *m was deleted, as in Sanskrit अश्नः áśnaḥ (from Proto-Indo-European *h₂éḱmnes 'anvil [gen. sg.]'). The sequence remains if the *-mn- sequence is heterosyllabic, such as in Ancient Greek πρύμνος prýmnos 'prominent'. The law was first discovered by Johannes Schmidt in 1895 and is named for the Avestan reflex 𐬀𐬯𐬥𐬋 asnō.[1][2]
aspirate throwback
(Ancient Greek, Sanskrit) Also, aspiration throwback. When a root-final aspirated stop loses its aspiration for whatever reason, typically due to another process, the aspiration is retracted to the initial consonant whenever that initial consonant is capable of taking an aspirated quality.[3][4] One example includes the Ancient Greek root τρίχ- tríkh- 'hair', which becomes θρίξ thríx in the nominative form.[3] The process was mentioned earlier by the Sanskrit scholar Pāṇini, but brought to modern scholarship in the first clause of a two-part law proposed by Hermann Grassmann in 1863,[5] though the name "aspirate throwback" appears later.[3][a] The second clause is now referred to alone as Grassmann's law.[3]
Bartholomae's law
Main article: Bartholomae's law
Also, Buddha rule. If a cluster of two or more obstruents contains at least one voiced aspirated consonant, the whole cluster becomes voiced and aspirated. The process may have been inherited from Proto-Indo-European, though this is not universally accepted.[6] The law is named after the German linguist Christian Bartholomae who discussed outcomes of the process in the various Indo-Iranian languages in 1882.[7] The alternative name stems from the fact that the etymon for the Sanskrit word बुद्ध buddhá 'awake, enlightened' is affected by this process, derived from *bʰewdʰ 'to be awake' + *-tó-, the passive past participle suffix.[8][9]
boukólos rule
Main article: boukólos rule
Labiovelars lose their labialization and become plain velars when preceded or followed by *w or *u.[10][11] This dissimilatory process explains the reflex in words like Ancient Greek βουκόλος boukólos 'cowherd', derived from Proto-Indo-European *gʷoukʷólos. The expected form *βουπόλος boupólos does not appear because the initial *kʷ in *kʷólos is preceded by the *u in *gʷou-, whereas in αιπόλος aipólos 'goatherd', the expected form -πόlos -pólos is attested, derived from Proto-Indo-European *ai(ǵ)kʷólos.[10] This process remained productive into Proto-Germanic, where it also came to apply to labiovelars preceded by *-un- through an assimilatory process which caused *n to have a labialized allophone.[11] Examples of this include Proto-Germanic *tungōn- 'tongue' from Proto-Indo-European *dn̥ǵʰwéh₂- both meaning 'tongue', whence both Latin lingua (from Old Latin dengua) and English tongue (from Old English tunge).[12]
Dybo's law
Not to be confused with Dybo's law in Proto-Slavic.
Laryngeal consonants are lost between a vowel and any other consonant in pretonic syllables.[13][14] Examples of this include Proto-Celtic *wiro- (whence Old Irish fer 'man'), Latin vir 'man', and Old English wer 'man', all of which are derived from Proto-Indo-European *wiHró-. If the vowel is long before the process occurs, it is shortened.[13][15] The process likely did not take place in Proto-Indo-European as it only affected the western Indo-European languages; examples from eastern families show laryngeal retention, such as Lithuanian výras 'man, husband' and Sanskrit वीरः vīráḥ 'man, hero'.[16] The law is named for Vladimir Dybo, who published work on the topic in 1961.[17]
Grassmann's law
Main article: Grassmann's law
(Ancient Greek, Sanskrit) Also, ha-ha rule; breath dissimilation. When an aspirated consonant is followed by another aspirated consonant in same or following syllable, the first consonant loses its aspiration. Examples of pairs affected by this process include Ancient Greek θρίξ thríx 'hair' in the nominative case, but τριχός trikhós in the genitive case.[18][19] Hermann Grassmann first proposed this process in 1863 as the second clause of a two-part law. The first clause is now known as the aspirate throwback.[18] The law remained productive after the Greek devoicing of aspirates and /h/,[b] from earlier *s, which behaved as an aspirated stop.[21]
Kortlandt effect
Proto-Indo-European *d undergoes debuccalization, becoming the laryngeal *h₁, whenever it is followed by a dental consonant, a consonant followed by a dental, or whenever the following syllable begins with a dental.[22] Examples include Ancient Greek ἑκατόν hekatón 'one hundred' from *dḱm̥tom, where the simple loss of the initial *d is attested in forms like Latin centum and Sanskrit शतम् śatám, but the debuccalization of *d instead of deletion adequately explains the initial vowel in the Greek term.[23] The process also explains the relationship between the Ancient Greek terms δρέπω drépō 'I pluck', from the Proto-Indo-European root *drep-, and Homeric Greek *ἐρέπτομαι *eréptomai 'I feed on, I munch',[c] from the same root affected by the debuccalization (*h₁rep-).[26] The law is named after Frederik Kortlandt, who first proposed the sound change in 1983.[27][28] The debuccalization appears to have taken place before the Anatolian languages split off from Proto-Indo-European.[29]
Kuiper's law
Laryngeals are lost in utterance-final position immediately preceding a pause.[30] The process does not cause compensatory lengthening.[31] The law is named for the Dutch linguist F. B. J. Kuiper, who published work on this process in 1955.[32][33]
*kʷetwóres rule
Main article: *kʷetwóres rule
In a word of three syllables with a vowel pattern *é-o-V, where V is any vowel, the accent is moved forward to the middle syllable, becoming *e-ó-V. This explains the penultimate accent in terms like Vedic Sanskrit चत्वारः catvā́raḥ, the nominative plural form of 'four', from Proto-Indo-European *kʷetwóres. The law is named after this example.[34]
neognós rule
Laryngeals are lost in zero-grade contexts where full-grade root contains a consonant–vowel–resonant–laryngeal string, in that order, in certain reduplicated forms and in some other compounds. Examples include the Ancient Greek term νεογνός neognós 'newborn'; the Greek term is derived from Proto-Indo-European *newoǵn̥h₁o- through a medial form *newoǵno-.[16][35]
Osthoff's law
Main article: Osthoff's law
(All but Indo-Iranian and Tocharian) When a long vowel is followed by a sonorant and another consonant in the same syllable, it is shortened.
Pinault's law
Main article: Pinault's law
Also, Pinault's rule. Laryngeals are dropped in word-medial position between a consonant and *y, such as in Latin socius 'friend' from Proto-Indo-European *sokʷh₂-yo-.[14][36] Only *h₂ and *h₃ appear to have been affected,[36] though the law has been invoked to explain instances of *h₁'s disappearance in the same context, such as Proto-Celtic *gan-yo- 'to be born' from Proto-Indo-European *ǵnh₁yetor.[37] The law is named for the French linguist Georges-Jean Pinault.[36]
ruki sound law
Main article: ruki sound law
(Balto-Slavic, Albanian, Armenian, Indo-Iranian) Also, ruki rule; iurk rule. *s is retracted to a postalveolar *š when preceded by *r, *u, *k or *i. This also includes *g and *gʰ, which are devoiced before *s, and also the allophones *r̥, *w, *y. But it does not include the palatovelar *ḱ. In Indo-Iranian, it is also triggered by *l, which merges with *r. In Slavic, *š is further retracted to *x unless followed by a front vowel or *j.
Siebs's law
Main article: Siebs's law
If an s-mobile is added to a root that begins with a voiced consonant, that consonant is devoiced. If it is aspirated, it retains its aspiration.
Stang's law
Main article: Stang's law
Word-finally, when a laryngeal, *y or *w is preceded by a vowel and followed by a nasal consonant, it is dropped and the preceding vowel is lengthened.
Szemerényi's law
Main article: Szemerényi's law
1.  In pre-Proto-Indo-European, the word-final fricatives *s and *h₂ are deleted in following a vowel–resonant sequence, followed by compensatory lengthening.[1] Some linguists include in the law a process where if the resulting sequence is *-ōn, the *n is also dropped, but others describe that deletion as a separate process.[38]
2.  Also, broad Szemerényi's law; final Szemerényi's law. In pre-Proto-Indo-European, syllable-final fricatives are deleted following a vowel–consonant sequence, followed by compensatory lengthening. The process is blocked if the consonant preceding the fricative is in a cluster or if the following syllable begins with a consonant.[39][40]
weather rule
Laryngeals are lost in word-medial position preceding a stop followed by a resonant and a vowel. The law is named for its reflex in English, weather, which is derived from Proto-Indo-European *weh₁dʰrom 'weather'; the laryngeal *h₁ is deleted before the sequence *-dʰro- which comprises a stop, a resonant, and a vowel, respectively.[16] The law does not cause compensatory lengthening.[31]
Weise's law
Main article: Weise's law
Palatovelar consonants *ḱ *ǵ *ǵʰ are depalatalized when preceding *r. The law is named after the German linguist Oskar Weise who observed the results of the change in a 1881 essay on the topic.[41]

Albanian

[edit]
A map of the Albanian dialects
Rosenthall's law
Within a morpheme, only one nasal–stop cluster is allowed; if more than one cluster exists in the underlying representation, any of these clusters created by morphophonological processes, such as epenthesis, are deleted.[42] Examples are found in the terms kuvend 'assembly' and mbrëmë 'last night', where the respective expected epenthetic forms *nguvend and *mbrëmbë reduced following this process.[43] The process has been likened to Lyman's law in Japanese and Grassmann's law in Ancient Greek and Sanskrit.[44] The law is named for the American linguist Samuel Rosenthall [Wikidata] who first proposed the process in 2022.[42]

Balto-Slavic

[edit]
Lidén's law
Word-initial *w in Proto-Indo-European is lost before non-syllabic *r and *l as the language developed into Proto-Balto-Slavic.[45] This process is named for the Swedish linguist Evald Lidén [sv; no; hy], who wrote about the process in 1899.[46] The process described by the law likely occurred after the development of Hirt's law, but before the syllabification of resonants. While it is possible that the law occurred after the syllabification of resonants and only affected non-syllabic resonants, Ranko Matasović finds this "improbable on phonetic grounds".[47]
Hirt's law
Main article: Hirt's law
Also, Hirt–Illich-Svitych's law. If the syllable preceding the expected stressed syllable has a vowel immediately followed by a laryngeal, the stress is retracted to that syllable. The law was first proposed by the German philologist Hermann Hirt in 1895, but the original formulation was corrected in 1963 by the Soviet linguist Vladislav Illich-Svitych. Examples include comparisons of Lithuanian výras 'man, husband' and mótė 'mother' with Sanskrit वीरः vīráḥ 'man, hero' and माता mātā́ 'mother', respectively.[48] The law applies to the original PIE accent placement, but after leveling of PIE mobile-accented paradigms into end-stressed paradigms. It also applied before the epenthesis before syllabic sonorants.
Pedersen's law
Main article: Pedersen's law
In words with a Balto-Slavic mobile accent paradigm, the accent was retracted from a medial onto the initial syllable. In Proto-Slavic, a similar analogical change caused the retraction of the accent onto a preceding unaccented clitic, such as a preposition.
Winter's law
Main article: Winter's law
Short vowels with non-acute accents are lengthened before unaspirated voiced stops (*b, *d, *g, but not *ǵ). The newly lengthened vowel receives the acute accent.[49] The law is named after the German linguist Werner Winter who wrote his proposal in 1976, though it was not published until 1978.[50] Frederik Kortlandt has dated the law to the final years of the Balto-Slavic period.[51]

Baltic

[edit]
de Saussure's law
(Lithuanian) Also, Saussure's law. If a non-acuted accented syllable is followed by an acuted syllable, the accent shifts forwards onto the acuted syllable. This split the Balto-Slavic fixed accent paradigm into Lithuanian paradigms 1 and 2, and the mobile accent paradigm into paradigms 3 and 4.
Hjelmslev's law
(Lithuanian) When a vowel receives an accent, it takes on the intonation of the following syllable.[52] The law is named for the Danish linguist Louis Hjelmslev, who proposed the process in his doctoral thesis in 1932.[53] Frederik Kortlandt states that, if the ictus retracts to a laryngealized vowel, the laryngeal is deleted and the result is a rising tone, but N. E. Collinge argues this is beyond the scope of process and that both Hjelmslev and de Saussure allow for a falling tone in their analyses.[54][55]
Leskien's law
(Lithuanian) If a word-final long vowel contains a falling accent, it is shortened. This process precedes Hjemslev's law, but is preceded by de Saussure's and Nieminen's laws.[56] The law is named for August Leskien, who first established the law in 1881.[57][58]
Nieminen's law
When the Proto-Baltic sequence *-ás is found word-finally, it is reduced to *-əs and loses its ability to carry stress. As a result, final stress is retracted to the penultimate syllable. This change explains the accentuation paradigm of o-stem nouns. Examples include báltas 'white' and var̃nas 'raven' from earlier *langás and *warnás, respectively. This is contrasted with mobile paradigms, where the accent is final, such as in galvà 'head' and žvėrìs 'beast'.[59] The process certainly precedes Leskien's law in Lithuanian, but has been suggested to go at least as far back as Proto-Baltic based on evidence from Old Prussian.[60] The law is named after the Finnish linguist Eino Nieminen [fi; lt; eo; pl] who proposed the law in 1922.[59][61]

Slavic

[edit]

Dybo's law
Main article: Dybo's law
Also, Dybo–Illich-Svitych's law. If a syllable was non-acute and accented, the accent was advanced onto the following syllable. The originally accented syllable retains its length. The change was prevented if the word had a mobile accent paradigm.
fall of the weak yers
Not to be confused with fall of the yers.
Following the results of Havlík's law, weak yers were deleted. Examples are found in Old East Slavic, where earlier forms for the word 'prince' demonstrate a retained yer (кънѧзь kъnjazь), but later forms show it without (кнѧзь knjazь); the retained forms are dated to around 1075, while loss became widespread between the 1120s and 1210s.[62]
Havlík's law
Main article: Havlík's law
In late Proto-Slavic, the vowels represented by *ь and *ъ, called yers, become "weak" – that is, subject to moraic shortening – in final position or if they are followed by a vowel other than another yer. A yer becomes "strong" if the following syllable contained a weak yer. In words with three successive syllables all containing yers, the final yer was weak, causing the penultimate syllable to be strong and the antepenultimate weak.[62] This process represents the first phase of the larger yer shift, where the second phase is known as the fall of the weak yers, where weak yers were deleted.[62]
Ivšić's law
Main article: Ivšić's law
Also, Stang's law;[d] Stang–Ivšić's law. Accented weak yers, as according to Havlík's law, lost their accent to the preceding syllable, which received a "neoacute" accent.
law of open syllables
Main article: History of Proto-Slavic § Elimination of syllable codas
Also, opening of syllables; tendency to rising sonority. Word- and syllable-final obstruents and obstruent clusters are deleted. Finals nasals are lost after short vowels and nasalized after long vowels.[63]
Meillet's law
Main article: Meillet's law
In words with a mobile accent paradigm, if the first syllable is accented with a rising (acute) accent, it is converted into a falling (circumflex) accent.
Shakhmatov's law
(No longer widely accepted) Also, Šaxmatov's law. Slavic short falling (circumflex) accents shift leftward (i.e., to the preceding syllable).[64]
Slavic first palatalization
Main article: Slavic first palatalization
Also, first palatalization of velars; first regressive palatalization. When the velar sounds *k, *g, and *x occur before front vowels and *y, they undergo palatalization and become *č, *ž, and *š, respectively. If the velar follows a sibilant (i.e., *sk or *zg), the sibilant was backed to *šč and *ždž before the cluster was reduced in some dialects to *št and *žd.[65] The process was probably mediated by coronalization before a final assibilation. The time at which the process occurred is unknown but it must have occurred prior to the Migration Period and was completed sometime between the 6th and 8th centuries.[66]
Slavic second palatalization
Main article: Slavic second palatalization
Also, second palatalization of velars; second regressive palatalization. Following the monophthongization of Proto-Slavic *ai to *ě in open syllables and *i in closed syllables, velars became palatalized again. The process had different outcomes based on dialect: *k typically became *c and *g became either *dz or simply *z, but *x became *š in West Slavic, *xʲ in Novgorodian, and *s elsewhere. The process is estimated to have happened around the same time the West Slavs were migrating north of Carpathia and the Novgorodians were migrating to what is now northwestern Russia.[67] Like the first palatalization, the process occurred in several stages: palatal coarticulation, palatalization, and assibilation. It appears that Novgorodian only went through the first stage.[68] Clusters that had originally contained *ku̯ underwent palatalization in South Slavic and some East Slavic unless it was preceded by *s, but West Slavic and Novgorodian did not experience this palatalization at all.[69]
Slavic third palatalization
Main article: History of Proto-Slavic § Progressive palatalization
Also, progressive velar palatalization; palatalization of Baudouin de Courtenay. When Proto-Slavic *i, *i, or *in precede a velar, the velar is palatalized and then assibilated; *k and *g become *c and *dz, respectively, in all languages, with *dz undergoing further lenition to *z outside of Eastern South Slavic, Slovak, and Lechitic. In West Slavic, *x became *š, but *s or *sʲ in South and East Slavic.[70] Examples of this process include earlier *liːkad 'face', which became *liːca (whence Old Czech líce), and *mεːsinkaːd, the genitive singular form of 'moon', which became *mεːsĩːcaː (whence Old Polish miesięca).[70] The first stage of this process was in effect by the 6th and 7th centuries.[71]
Stang's law
If a word-final syllable was long falling (circumflex) accented, the accent was retracted onto the preceding syllable. The originally accented syllable is shortened, and the newly-accented syllable receives a "neoacute" accent. This change applied after Dybo's law, and often "undid" it by shifting the accent back again.
Van Wijk's law
Short vowels, except for yers (*ь, *ъ) and nasal vowels, are lengthened when preceded by a palatal consonant.[citation needed] Although Aleksey Shakhmatov was the first to suggest the process in 1898, the law is named for the Dutch linguist Nicolaas van Wijk, who published work on the process in 1916.[72][73]
yer shift
Not to be confused with fall of the weak yers.
Also, jer shift; third Slavic vowel shift; fall of the yers. The yer vowels, *ь and *ъ, underwent two-part process followed by a third step that fractured the realization of the vowel qualities. First, yer vowels underwent an alternating pattern of weakening every other yer in a word beginning with weakening the final one; this first part of the shift is referred to as Havlík's law.[74] The process is a patterned form of compensatory lengthening.[75] Next, the weak yers were deleted, referred to as the fall of the weak yers.[62] Following this deletion, the remaining strong yers were thereby shifted to different vowel qualities in the various Slavic languages, which collectively are known as the vocalization of the yers.[76][77]

Celtic

[edit]

Joseph's law
During the period between Proto-Indo-European and Proto-Celtic, when *e is followed by a resonant then by *a, the *e assimilates to *a. In other words, in the sequence *eRa, where *R signifies any resonant, *e becomes *a, thereby becoming *aRa.[78][79] Examples of this change include Proto-Celtic *taratro- 'drill' (whence Irish tarathar 'auger') from earlier *teratro-, derived from Proto-Indo-European terh₁tro- (whence Ancient Greek τέρετρον téretron 'borer, gimlet'). The law does not affect *ā and probably did not affect environments where the *a was word-final.[78] The law also appears to have affected words where the *a was formerly a laryngeal consonant in Proto-Indo-European, such as in Proto-Celtic *banatlo- 'broom plant' which may be derived from Proto-Indo-European *bʰenH-tlo from a root meaning 'to hit, to strike'.[80] The process was expanded in Welsh include environments where the resonant is followed by a nasal, explaining the vowel quality in Welsh words like sarnu 'to trample' but not Old Irish sernaid 'to arrange, to order', both from a Proto-Celtic *sternū/*starnati paradigm (from an older subjunctive Proto-Indo-European form *ster-nh₂-e/o, cognate with Latin sternō).[81] Similarly, another expansion of the process appears in both Brittonic and Gaulish, causing the assimilation of *o to *a in the resonant–vowel environment *oRa, thereby rendering *aRa. Compare Middle Welsh taran 'thunder' and Gaulish Taranis 'the Celtic god of thunder', which were affected by the expanded law, with Old Irish torann 'thunder', which was not.[82] The law is named after Lionel Joseph who covered the topic in 1982.[78][80]
MacNeill's law
Main article: Phonological history of Old Irish § MacNeill's law
(Old Irish) Also, MacNeill–O'Brien's law. Lenition of Old Irish n, r, and l is lost in final unstressed syllables even though they are etymologically expected to be lenited in that position.[83][84]
McCone's law
Main article: Phonological history of Old Irish § McCone's law
1.  Proto-Celtic *b and *u̯ become *β before *n word-internally. The latter change is rare, but occurs in words like Old Irish amnair 'maternal uncle' from Proto-Celtic *au̯n and omun 'fear' from *ɸoβnos. The law appears to have only occurred in contexts where there is no front vowel preceding the cluster, which accounts for apparent counterexamples like Welsh clun 'hip, haunch' from Proto-Indo-European *ḱlownis and Old Irish búan 'permanent' from *bʰewHnos, though some other etymologies account for different sources; the Welsh example may be a later borrowing from Latin clūnis, for example. The law shares a relationship to another Proto-Celtic sound change where *ɸ became *u̯ between either *a or *o and *n.[85]
2.  (Old Irish) Unless the syllable is stressed, voiceless obstruents are voiced word-initially and word-finally.[86]

Germanic

Cowgill's law of Germanic
Main article: Cowgill's law of Germanic
(Not fully accepted) When preceded by a sonorant and followed by *w, the PIE laryngeal *h₃ (and possibly also *h₂) appears as *k in Proto-Germanic after the application of Grimm's law.
Germanic spirant law
Main article: Germanic spirant law
Also, Primärberühung. When a plosive is followed by any voiceless sound, normally *s or *t, it becomes a voiceless fricative and loses its labialization if present. A dental consonant followed by *s becomes *ss, and followed by *t becomes either *ss (in older inherited forms) or *st (in newer and productive forms).
Grimm's law
Main article: Grimm's law
Also, first Germanic sound shift; first Germanic consonant shift; Rask's rule. The three series of Proto-Indo-European plosives undergo a chain shift. The first shift causes voiceless stops – *p, *t, *k, and *kʷ – to become the voiceless fricatives *f, *θ, *x, and *xʷ, respectively.[e] Next, the plain voiced stops – *b, *d, *g, and *gʷ – devoice and become *p, *t, *k, and *kʷ, respectively. Lastly, the aspirated voiced stops – *bʰ, *dʰ, *gʰ, and *gʷʰ – become voiced stops *b, *d, *g, and *gʷ, respectively.[92] This sound change is sometimes obfuscated in Old High German as a result of the High German consonant shift.[93] The process did not affect the second consonant in a cluster of two adjacent obstruents. Compare two versions of the Old Frisian word for 'throat': strot- and throt-. Both are derived from the Proto-Indo-European s-mobile root *(s)trewd-, the former including the s-mobile while the latter does not. In this example, the form with the s-mobile blocks the assibilation of the *t.[89] Several other exceptions are covered by Verner's law.[94] The Danish linguist Rasmus Rask is credited with first articulating the law in 1818, but its more common name is from German folklorist Jacob Grimm, who – after reading Rask's work – expanded on it and published it in the preface of his German grammar book in 1819 with a rewrite in 1822.[95]
Holtzmann's law
Main article: Holtzmann's law
(North and East Germanic) Also, Verschärfung; sharpening; intensification. The geminated glides *jj and *ww are hardened into geminate plosives. In North Germanic, *jj becomes *ggj, while it became *ddj in East Germanic, *ww becomes *ggw in both.[96]
Ingvaeonic nasal spirant law
Main article: Ingvaeonic nasal spirant law
(Ingvaeonic languages) When followed by a fricative, /n/ is lost and the preceding vowel is lengthened and nasalized.
Kluge's law
Main article: Kluge's law
(Not generally accepted) PIE plosives merge with a following *n and become geminate voiceless plosives in Germanic.
Sievers's law
Main article: Sievers's law
Suffixal *j alternates with *ij depending on the syllable weight (length) of the preceding morpheme. *j appears after "light" or "short" morphemes, which consist of a single syllable ending in a short vowel and a single consonant. *ij appears elsewhere, including all morphemes with more than one syllable.
Thurneysen's law
Main article: Thurneysen's law
(Gothic) Spirants in unaccented syllables changed their voiced–unvoiced quality based on the quality of the preceding consonant, whereby voiced spirants appear after unvoiced consonants and voiceless spirants appear after voiced consonants. Examples of both can be found in the dative singular forms, 𐌰𐌲𐌹𐍃𐌰 agisa 'fear' and 𐍂𐌹𐌵𐌹𐌶𐌰 riqiza 'darkness'.[97][f] In short, spirants are voiced when they are immediately preceded by a vowel without primary stress and the preceding consonant before the vowel is unvoiced. If the preceding consonant is a cluster where the second consonant is a liquid, the spirant remains unvoiced, but if the second consonant is a glide, it is voiced.[99] The process does not affect word-final spirants and the second element in a compound word where the simplex is stress-bearing. While some exceptions occur due to morphological leveling, there are at least seven words for which Thurneysen could not supply an explanation.[100] The law is named after the Swiss linguist Rudolf Thurneysen who posited the law in 1896 and published it in 1898.[101]
Verner's law
Main article: Verner's law
After the application of Grimm's law, when a voiceless fricative is preceded by an unaccented syllable, it is voiced (*f, *þ, *h, *hʷ, *s > *b, *d, *g, *gʷ, *z). Following this, the mobile PIE accent is lost and all words receive stress on the first syllable.

Greek

[edit]
A map of Ancient Greek dialects
Bartoli's law
Main article: Ancient Greek accent § Bartoli's law
Also, Bàrtoli's law. In short–long metrical feet where oxytone stress is expected, the syllable becomes paroxytone before a word boundary. The law only occurs in anapestic (short–short–long) and cretic (long–short–long) contexts. An example of this process can be seen in Ancient Greek θυγάτηρ thygátēr 'daughter', in its nominative singular form, when contrasted with its accusative singular form θυγατέρα thygatéra and with the Sanskrit nominative singular दुहिता duhitā́ 'daughter'. While some exceptions can be attributed to analogical change, there are still some unexplained exceptions.[102] The law is named after the Italian linguist Matteo Bartoli, whose 1930 publication contrasted Sanskrit oxytone words with their Ancient Greek paroxytone cognates.[103]
Cowgill's law of Greek
Main article: Cowgill's law of Greek
Whenever Proto-Indo-European *o occurs between a resonant and a labial, it becomes Greek υ y.[104][105] The resonant and the labial can be on either side of the *o and produce the same output. Examples of a resonant followed by *o followed by a labial include (νύξ nýx 'night' from *nokʷt- (whence also Latin nox 'night'). This law is preceded by laryngeal coloring, meaning that Proto-Indo-European sequences of *h₁o, *h₃o, and *h₃e are also accounted for in the law, as are cases in which the zero-grade form was vocalized, such as in στόρνυμεν stórnymen 'we smooth out' from Proto-Indo-European *str̥-n-h̥₃-, showing the nasal infix. Some later sound changes obfuscate the law, but there is evidence to show that the sound change still occurred. For example, Proto-Indo-European *nomn̥ 'name' gave way to Proto-Greek *onuma. Although in Attic Greek the form became ὄνομα ónoma, the expected form ὄνυμα ónyma is found in both Doric and Aeolic Greek; the expected form is also found in derivatives such as ἀνώνυμος anṓnymos 'nameless, inglorious'.[104]
Vendryes's law
Main article: Ancient Greek accent § Vendryes's law
Also, Vendryès's law. Any perispomenon with a short vowel in the antepenultimate becomes proparoxytone in Attic. The law is named after the French linguist Joseph Vendryes.[106]
Wheeler's law
Main article: Ancient Greek accent § Wheeler's law
Also, law of dactylic retraction. Oxytone words in Proto-Indo-European become paroxytone in Ancient Greek if the word has a dactylic ending; in other words, the stress in dactylic words moved from the final syllable to the penultimate syllable.[106][107] The law counts endings such as ον -on, ος -os, and οι -oi as short. Examples of this tonic retraction include cognate pairs like ποικίλος poikílos 'variegated, complex', with a paroxytone, and Vedic Sanskrit पेशलः peśaláḥ. The law is named after the American philologist Benjamin Ide Wheeler who published work on the topic in 1885.[106][107]

Indo-Iranian

[edit]

Brugmann's law
Main article: Brugmann's law
When it is an ablaut alternant of *e, the vowel *o is lengthened and (after merging) becomes *ā when it stands at the end of a syllable.
Fortunatov's law
Main article: Fortunatov's law
(Sanskrit) When Proto-Indo-European *l precedes a dental consonant, the latter becomes a retroflex consonant and the *l is deleted. Examples include जठर jaṭhára 'belly', which is derived from Proto-Indo-European *ǵelt-, and कुठार kuṭāra 'ax', derived from *kult-. The law is named after the Russian linguist Filipp Fortunatov.[108]
law of the palatals
See also: Proto-Indo-Iranian language § Historical phonology
Also, Palatalgesetz. Proto-Indo-European *e palatalizes velar stops and becomes Proto-Indo-Iranian *a.[109] The process is preceded by the delabialization of the labiovelar consonants.[110][111] Although several linguists have attempted to identify the originator of the law and several have declared a supposed originator, no consensus has been reached.[112] According to N. E. Collinge, it appears that six different linguists – Hermann Collitz, Ferdinand de Saussure, Johannes Schmidt, Esaias Tegnér Jr., Vilhelm Thomsen, and Karl Verner – discovered the law "roughly simultaneously" and "in entire independence" from one another.[113]

Italic

[edit]
The Praeneste fibula is a golden brooch which contains an inscription considered to be the oldest surviving example of Old Latin, dated to the first half of the 7th century BC.[114]
Exon's law
Main article: History of Latin § Exon's law
In a word with four or more syllables, if the second and third syllable are short, then the vowel of the second syllable is syncopated, though it may be restored by analogy.
Lachmann's law
Main article: Lachmann's law
When a short vowel is followed by an underlyingly voiced stop followed by a voiceless stop, it is lengthened. The process explains the differences between verbal forms, such as agō 'I drive' and cadō 'I fall', and their respective derivatives, such as āctus 'made, done' and cāsus 'a fall'.[115] Although the law was popularized by Paul Kiparsky,[115] it is named for the German classicist Karl Lachmann who wrote about the process in 1850.[116] It is unclear if the law applied to the whole Italic language family, but it applied at least to Latin.[115]
pius law
Not to be confused with Thurneysen's law.
Also, Thurneysen's law. The Proto-Italic diphthong *ūy, derived from a Proto-Indo-European sequence of *u followed by a laryngeal and *i, is fronted to *īy. Examples include Oscan piíhiúí 'pious (dative singular)' and Latin pius 'pious', both from Proto-Italic *pīyo- derived from Proto-Indo-European *puh₂yo- 'pure'.[117] The root is shared with the Latin pūrus 'pure', derived from Proto-Indo-European *puH-ro- 'clean', which did not undergo this change.[118] Warren Cowgill argued that this law also occurred in Celtic in attempting to unify both Italic and Celtic into a double-jointed Italo-Celtic subfamily.[119]
Thurneysen–Havet's law
Not to be confused with Thurneysen's law or the pius law.
The Proto-Italic diphthong *ow becomes *aw before a vowel.[117][120] This process precedes the Proto-Italic rounding of the diphthong *ew to *ow. Examples include Latin caueō 'I am weary of', derived from Proto-Indo-European *kowh₁-eyo- (whence Ancient Greek κοέω koéō 'I am aware').[117] There appears to be some variation based on Roman social register and the process may also affect the inverted sequence *wo. For example, the Latin term vacuus exists alongside vocīuus in the work of some comedians, including in Casina, a play written by Plautus. The law is named for the Swiss linguist Rudolf Thurneysen and the French classicist Louis Havet, who appear to have developed the concept largely independently of each other in 1884 and 1885, respectively.[121]
