Sanskrit grammar

This article is about the grammar of Classical Sanskrit. For the earlier language, see Vedic Sanskrit grammar.

The grammar of the Sanskrit language has a complex verbal system, rich nominal declension, and extensive use of compound nouns. It was studied and codified by Sanskrit grammarians from the later Vedic period (roughly 8th century BCE), culminating in the Pāṇinian grammar of the 6th century BCE.

Grammatical tradition

Main article: Vyākaraṇa

Sanskrit grammatical tradition (vyākaraṇa, one of the six Vedanga disciplines) began in late Vedic India and culminated in the Aṣṭādhyāyī of Pāṇini, which consists of 3990 sutras (ca. 5th century BCE). About a century after Pāṇini (around 400 BCE), Kātyāyana composed vārtikas (explanations) on the Pāṇinian sũtras. Patañjali, who lived three centuries after Pāṇini, wrote the Mahābhāṣya, the "Great Commentary" on the Aṣṭādhyāyī and Vārtikas. Because of these three ancient Sanskrit grammarians this grammar is called Trimuni Vyākarana. Jayaditya and Vāmana wrote a commentary named Kāśikā in 600 CE. Kaiyaṭa's (12th century AD) commentary on Patañjali's Mahābhāṣya also exerted much influence on the development of grammar, but more influential was the Rupāvatāra of Buddhist scholar Dharmakīrti which popularised simplified versions of Sanskrit grammar.

The most influential work of the Early Modern period was Siddhānta-Kaumudī by Bhaṭṭoji Dīkṣita (17th century) and its various derivate versions by Varadarāja.

European grammatical scholarship began in the 18th century with Jean François Pons and others, and culminated in the exhaustive expositions by 19th century scholars such as Otto von Böhtlingk, William Dwight Whitney, Jacob Wackernagel and others.

Verbs

Main article: Sanskrit verbs

Classification of verbs

Sanskrit has ten classes of verbs divided into two broad groups: intransitive and transitive. The thematic verbs are so called because an a, called the theme vowel, is inserted between the stem and the ending. This serves to make the thematic verbs generally more regular. Exponents used in verb conjugation include prefixes, suffixes, infixes, and reduplication. Every root has (not necessarily all distinct) zero, guṇa, and vṛddhi grades. If V is the vowel of the zero grade, the guṇa-grade vowel is traditionally thought of as a + V, and the vṛddhi-grade vowel as ā + V.

Tense systems

Sanskrit has ten tenses (plus one used in the Vedas, the "leT"). The verb tenses (a very inexact application of the word, since more distinctions than simply tense are expressed) are organized into four 'systems' (as well as gerunds and infinitives, and such creatures as intensives/frequentatives, desideratives, causatives, and benedictives derived from more basic forms) based on the different stem forms (derived from verbal roots) used in conjugation. There are four tense systems:

• Present (Present, Imperfect, Imperative, Optative)
• Perfect
• Aorist
• Future (Future, Conditional)

Present system

The present system includes the present tense and the imperfect (past imperfective), the optative and imperative moods, as well as some of the remnant forms of the old subjunctive. The tense stem of the present system is formed in various ways. The numbers are the native grammarians' numbers for these classes.

Perfect system

The perfect system includes only the perfect. The stem is formed with reduplication as with the present system.

The perfect system also produces separate "strong" and "weak" forms of the verb—the strong form is used with the singular active, and the weak form with the rest.

Aorist system

The aorist system includes aorist proper (with past indicative meaning, e.g. abhūḥ "you were") and some of the forms of the ancient injunctive (used almost exclusively with mā in prohibitions, e.g. mā bhūḥ "don't be"). The principal distinction of the two is presence/absence of an augment – a- prefixed to the stem. The aorist system stem actually has three different formations: the simple aorist, the sibilant aorist, and the reduplicating aorist, which is semantically related to the causative verb.

Future system

The future system is formed with the suffixation of sya or iṣya and guṇa. Verbs then conjugate as though they were thematic verbs in the present system. The imperfect of the future system is used as a conditional.

Verbs: conjugation

Each verb has a grammatical voice, whether active, passive or middle. There also is an impersonal voice, which can be described as the passive voice of intransitive verbs. Sanskrit verbs have an indicative, an optative and an imperative mood. Older forms of the language had a subjunctive, though this had fallen out of use by the time of Classical Sanskrit.

Basic conjugational endings

Conjugational endings in Sanskrit convey person, number, and voice. Different forms of the endings are used depending on what tense stem and mood they are attached to. Verb stems or the endings themselves may be changed or obscured by sandhi.

		Active			Middle
	Person	Singular	Dual	Plural	Singular	Dual	Plural
Primary	1	mi	váḥ	máḥ	é	váhe	máhe
	2	si	tháḥ	thá	sé	ā́the	dhvé
	3	ti	táḥ	ánti, áti	té	ā́te	ánte, áte
Secondary	1	am	vá	má	í, á	váhi	máhi
	2	ḥ	tám	tá	thā́ḥ	ā́thām	dhvám
	3	t	tā́m	án, úḥ	tá	ā́tām	ánta, áta, rán
Perfect	1	a	vá	má	é	váhe	máhe
	2	tha	áthuḥ	á	sé	ā́the	dhvé
	3	a	átuḥ	úḥ	é	ā́te	ré
Imperative	1	āni	āva	āma	āi	āvahāi	āmahāi
	2	dhí, hí,—	tám	tá	svá	ā́thām	dhvám
	3	tu	tā́m	ántu, átu	tā́m	ā́tām	ántām, átām

Primary endings are used with present indicative and future forms. Secondary endings are used with the imperfect, conditional, aorist, and optative. Perfect and imperative endings are used with the perfect and imperative respectively.

Nominals

Main article: Sanskrit nouns

Sanskrit is a highly inflected language with three grammatical genders: masculine (Template:Lang-sa2 puṃliṅga), feminine (Template:Lang-sa2 strīliṅga), and neuter (Template:Lang-sa2 napuṃsakaliṅga); and three numbers: singular (Template:Lang-sa2 ekavacanam), dual (Template:Lang-sa2 dvivacanam), and plural (Template:Lang-sa2 bahuvacanam). It has eight cases: nominative, vocative, accusative, instrumental, dative, ablative, genitive, and locative.

The number of actual declensions is debatable. Pāṇini identifies six kārakas corresponding to the nominative, accusative, dative, instrumental, locative, and ablative cases. Pāṇini defines them as follows (Ashtadhyayi, I.4.24 – 54):

1. Apādāna (lit. 'take off'): "(that which is) firm when departure (takes place)." This is the equivalent of the ablative case, which signifies a stationary object from which movement proceeds.
2. Sampradāna ('bestowal'): "he whom one aims at with the object". This is equivalent to the dative case, which signifies a recipient in an act of giving or similar acts.
3. Karaṇa ("instrument") "that which effects most." This is equivalent to the instrumental case.
4. Adhikaraṇa ('location'): or "substratum." This is equivalent to the locative case.
5. Karman ('deed'/'object'): "what the agent seeks most to attain". This is equivalent to the accusative case.
6. Kartā ('agent'): "he/that which is independent in action". This is equivalent to the nominative case. (On the basis of Scharfe, 1977: 94)

The genitive (sambandha) and vocative (sambodhana) cases are not equivalent to any kāraka in Pāṇini's grammar.

In this article they are divided into five declensions. The declension to which a noun belongs to is determined largely by form.

Basic noun and adjective declension

The basic scheme of suffixation is given in the table below—valid for almost all nouns and adjectives. However, according to the gender and the ending consonant/vowel of the uninflected word-stem, there are predetermined rules of compulsory sandhi which would then give the final inflected word. The parentheses give the case-terminations for the neuter gender, the rest are for masculine and feminine gender. Both Devanagari script and IAST transliterations are given.

Case name	Case number	Singular	Dual	Plural
Nominative (Template:Lang-sa2 kartā)	1	Template:Lang-sa2 -s (Template:Lang-sa2 -m)	Template:Lang-sa2 -au (Template:Lang-sa2 -ī)	Template:Lang-sa2 -as (Template:Lang-sa2 -i)
Accusative (Template:Lang-sa2 karma)	2	Template:Lang-sa2 -am (Template:Lang-sa2 -m)	Template:Lang-sa2 -au (Template:Lang-sa2 -ī)	Template:Lang-sa2 -as (Template:Lang-sa2 -i)
Instrumental (Template:Lang-sa2 karaṇa)	3	Template:Lang-sa2 -ā	Template:Lang-sa2 -bhyām	Template:Lang-sa2 -bhis
Dative (Template:Lang-sa2 sampradāna)	4	Template:Lang-sa2 -e	Template:Lang-sa2 -bhyām	Template:Lang-sa2 -bhyas
Ablative (Template:Lang-sa2 apādāna)	5	Template:Lang-sa2 -as	Template:Lang-sa2 -bhyām	Template:Lang-sa2 -bhyas
Genitive (Template:Lang-sa2 sambandha)	6	Template:Lang-sa2 -as	Template:Lang-sa2 -os	Template:Lang-sa2 -ām
Locative (Template:Lang-sa2 adhikaraṇa)	7	Template:Lang-sa2 -i	Template:Lang-sa2 -os	Template:Lang-sa2 -su
Vocative (Template:Lang-sa2 sambodhana)		Template:Lang-sa2 -s (Template:Lang-sa2 -)	Template:Lang-sa2 -au (Template:Lang-sa2 -ī)	Template:Lang-sa2 -as (Template:Lang-sa2 -i)

The final Template:Lang-sa2 (s) characters in the above table are theoretical. In Classical Sanskrit, all of them become Template:Lang-sa2 (ḥ) when the word is at the end of a sentence, and, if the word is followed by another in a sentence, the rules of sandhi for final "-ḥ" are applied.

a-stems

A-stems (/ɐ/ or /aː/) comprise the largest class of nouns. As a rule, nouns belonging to this class, with the uninflected stem ending in short-a (/ɐ/), are either masculine or neuter. Nouns ending in long-A (/aː/) are almost always feminine. A-stem adjectives take the masculine and neuter in short-a (/ɐ/), and feminine in long-A (/aː/) in their stems. This class is so big because it also comprises the Proto-Indo-European o-stems.

Numerals

The numbers from one to ten are:

1. éka-
2. dvá-
3. trí-
4. catúr-
5. páñca-
6. ṣáṣ-
7. saptá-, sápta-
8. aṣṭá-, áṣṭa-

10. dáśa-

All numbers in Sanskrit can be declined in all the cases. Numbers above four are only declined in the plural. Éka is declined like a pronominal adjective, though the dual form does not occur. Dvá appears only in the dual. Trí and catúr are declined irregularly:

Personal pronouns and determiners

Main article: Sanskrit pronouns and determiners

Sanskrit pronouns are declined for case, number, and gender. Many pronouns have alternative enclitic forms. The first and second person pronouns are declined for the most part alike, having by analogy assimilated themselves with one another. Ablatives in singular and plural may be extended by the syllable -tas; thus mat or mattas, asmat or asmattas. Sanskrit does not have true third person pronouns, but its demonstratives fulfil this function instead by standing independently without a modified substantive.

There are four different demonstratives in Sanskrit: tat, etat, idam, and adas. etat indicates greater proximity than tat. While idam is similar to etat, adas refers to objects that are more remote than tat. eta, is declined almost identically to ta. Its paradigm is obtained by prefixing e- to all the forms of ta. As a result of sandhi, the masculine and feminine singular forms transform into eṣas and eṣã.

The enclitic pronoun ena is found only in a few oblique cases and numbers. Interrogative pronouns all begin with k-, and decline just as tat does, with the initial t- being replaced by k-. The only exception to this are the singular neuter nominative and accusative forms, which are both kim and not the expected *kat. For example, the singular feminine genitive interrogative pronoun, "of whom?", is kasyãḥ. Indefinite pronouns are formed by adding the participles api, cid, or cana after the appropriate interrogative pronouns. All relative pronouns begin with y-, and decline just as tat does. The correlative pronouns are identical to the tat series.

In addition to the pronouns described above, some adjectives follow the pronominal declension. Unless otherwise noted, their declension is identical to tat.

• eka: "one", "a certain". (singular neuter nominative and accusative forms are both ekam)
• anya: "another".
• sarva: "all", "every". (singular neuter nominative and accusative forms are both sarvam)
• para: "the other". (singular neuter nominative and accusative forms are both param)
• sva: "self" (a reflexive adjective). (singular neuter nominative and accusative forms are both svam)

Compounds

Main article: Sanskrit compounds

One other notable feature of the nominal system is the very common use of nominal compounds, which in the later literary language may be huge (10+ words) as in some modern languages such as German and Finnish. Nominal compounds occur with various structures, however morphologically speaking they are essentially the same. Each noun (or adjective) is in its (weak) stem form, with only the final element receiving case inflection. The four principal categories of nominal compounds are:

• Dvandva (co-ordinative)

These consist of two or more noun stems, connected in sense with 'and'. Examples are rāma-lakşmaņau—Rama and Lakshmana, rāma-lakşmaņa-bharata-śatrughnāh—Rama, Lakshmana, Bharata and Satrughna, and pāņipādam—limbs, literally hands and feet, from pāņi = hand and pāda = foot.

• Tatpuruṣa (determinative)

There are many tatpuruṣas; in a tatpuruṣa the first component is in a case relationship with another. For example, a doghouse is a dative compound, a house for a dog; other examples include instrumental relationships ("thunderstruck") and locative relationships ("towndwelling").

• Karmadhāraya (descriptive)

A compound where the relation of the first member to the last is appositional, attributive or adverbial; e.g., uluka-yatu (owl+demon) is a demon in the shape of an owl. Karmadhārayas are considered by some to be tatpuruṣas.

• Bahuvrīhi (possessive/exocentric)

Bahuvrīhi compounds refer to a compound noun that refers to a thing which is itself not part of the compound. For example the word bahuvrīhi itself, from bahu = much and vrīhi = rice, denotes a rich person—one who has much rice.

Phonology

Further information: Śikṣā

Classical Sanskrit distinguishes about 36 phonemes. There is, however, some allophony and the writing systems used for Sanskrit generally indicate this, thus distinguishing 48 sounds. The sounds are traditionally listed in the order vowels (Ac), diphthongs (Hal), anusvara and visarga, plosives (Sparśa) and nasals (starting in the back of the mouth and moving forward), and finally the liquids and fricatives, written in IAST as follows:

An alternate traditional ordering is that of the Shiva Sutra of Pāṇini.

It should be understood that, while the script used here is Devanagari, this has no particular importance. It just happens currently to be the most popular script for Sanskrit. The form of the symbols used to write Sanskrit has varied widely geographically and over time, and notably includes in modern times the Tamil and other modern Indian scripts. What is important is that the adherence to the phonological classification of the symbols elucidated here has remained constant in Sanskrit since classical times. It should be further noted that the phonology of modern Indian languages has evolved, and the values given to Devanagari symbols in, e.g. Hindi, differ somewhat from those of Sanskrit.

Vowels

The vowels of Classical Sanskrit written in Devanagari, as a syllable-initial letter and as a diacritic mark on the consonant Template:Lang-sa2 (/p/), pronunciation transcribed in IPA, IAST, and approximate equivalent in English:

Letter	Template:Lang-sa2	IPA	IAST
Template:Lang-sa2	Template:Lang-sa2	[ɐ]	a	Although, as a more closed vowel, it markedly differs in quality from ā, phonologically it functions as its short counterpart.
Template:Lang-sa2	Template:Lang-sa2	[aː]	ā
Template:Lang-sa2	Template:Lang-sa2	[ɪ]	i
Template:Lang-sa2	Template:Lang-sa2	[iː]	ī
Template:Lang-sa2	Template:Lang-sa2	[ʊ]	u
Template:Lang-sa2	Template:Lang-sa2	[uː]	ū
Template:Lang-sa2	Template:Lang-sa2		ṛ
Template:Lang-sa2	Template:Lang-sa2		ṝ
Template:Lang-sa2	Template:Lang-sa2		ḷ
*Template:Lang-sa2	*Template:Lang-sa2		*ḹ	a theoretical sound that did not actually exist
Template:Lang-sa2	Template:Lang-sa2	[eː]	e	a long close-mid front unrounded vowel: a in bane (some speakers)
Template:Lang-sa2	Template:Lang-sa2	[ai]	ai	a diphthong: i in ice, i in kite (US, Canadian, and Scottish English)
Template:Lang-sa2	Template:Lang-sa2	[oː]	o	a close-mid back rounded vowel: o in bone (Scottish English)
Template:Lang-sa2	Template:Lang-sa2	[au]	au	a diphthong: ou in house (Canadian English)

The long vowels are pronounced twice as long as their short counterparts. Also, there exists a third, extra-long length for most vowels. This lengthening is called pluti; the lengthened vowels, called pluta, are used in various cases, but particularly in the vocative. The pluti is not accepted by all grammarians. The vowels /eː/ and /oː/ continue as allophonic variants of Proto-Indo-Iranian /ai/, /au/ and are categorised as diphthongs by Sanskrit grammarians even though they are realised phonetically as simple long vowels.

Additional points:

• There are some additional signs traditionally listed in tables of the Devanagari script:
  • The diacritic Template:Lang-sa2 called anusvāra (IAST: ṃ) represented a nasal sound with varied pronunciation (See also Anusvara § Sanskrit)
  • The diacritic Template:Lang-sa2 called visarga, represents voiceless glottal fricative (IPA: [h]) whose voiced counterpart is the consonant h [ɦ]
  • The diacritic Template:Lang-sa2 called candrabindu indicates the nasalization of a vowel before a consonant, or of the semi-vowels y, v, l.
• If a lone consonant needs to be written without any following vowel, it is given a virāma (or halanta) diacritic below (Template:Lang-sa2).
• The vowel /aː/ in Sanskrit is realised as being more central and less back than the closest English approximation, which is /ɑː/. But the grammarians have classified it as a back vowel.
• The ancient Sanskrit grammarians classified the vowels as velars, retroflexes, palatals and plosives rather than as back, central and front vowels. Hence Template:Lang-sa2 and Template:Lang-sa2 are classified respectively as palato-velar (a+i) and labio-velar (a+u) vowels respectively. But the grammarians have classified them as diphthongs and in prosody, each is given two mātrās. This does not necessarily mean that they are proper diphthongs, but neither excludes the possibility that they could have been proper diphthongs at a very ancient stage. These vowels are pronounced as long /eː/ and /oː/ respectively by priests of today. Other than the "four" diphthongs, Sanskrit usually disallows any other diphthong—vowels in succession, where they occur, are converted to semivowels according to sandhi rules.
• Vedic Sanskrit had syllabic /r/ and /l/ that were treated as vowels, but by Classical times these had broken to [ɽ] and [l] plus a vowel. Derivational morphology added a long version of the /r/. Indian pandits came to pronounce them as [ɽɪ], [lɪ] and [ɽiː] in the North - as in the name of the god known there as "krishn", - as [ɽʊ], [lʊ] and [ɽuː] in the South - where the same god is commonly referred to as "krushna", - and as [ɽɒ], [lɒ] and [ɽaː] in the East.

In the earlier language, Template:Lang-sa2 was pronounced as the labio-velar approximant [w], but it later developed into a labio-dental sound. To an English speaker's ear, this sound may be interpreted as the English "v" or the English "w", depending on context and precise articulation. Moreover, the Sanskrit व has a considerable range of articulation depending on position. . It is nonetheless understood in the Sanskrit writing system, as well as by speakers of modern Indian languages, as one and the same phoneme.

Stress

Vedic Sanskrit had pitch accent (see Vedic accent). However, by Classical Sanskrit this had been replaced by stress. Stress may not fall on the last syllable of a word, but otherwise it falls on the last heavy syllable (including CV syllables with the vowels e and o, which are long but often transcribed as if they were short). If all syllables before the last are light, then stress falls on the initial syllable. However, stress is not particularly important in Sanskrit.

Phonology and sandhi

The Sanskrit vowels are as discussed in the section above. The long syllabic l (ḹ) is not attested, and is only discussed by grammarians for systematic reasons. Its short counterpart ḷ occurs in a single root only, kḷp "to order, array". Long syllabic r (ṝ) is also quite marginal, occurring in the genitive plural of r-stems (e.g. mātṛ "mother" and pitṛ "father" have gen.pl. mātṝṇām and pitṝṇām). i, u, ṛ, ḷ are vocalic allophones of consonantal y, v, r, l. There are thus only 5 invariably vocalic phonemes: a, ā, ī, ū, ṝ.

Visarga ḥ Template:Lang-sa2 is an allophone of r and s, and anusvara ṃ, Devanagari Template:Lang-sa2 of any nasal, both in pausa (i.e., the nasalised vowel). The exact pronunciation of the three sibilants may vary, but they are distinct phonemes. Voiced sibilants, such as z /z/, ẓ /ʐ/, and ź /ʑ/ as well as its aspirated counterpart źh /ʑʱ/, were inherited by Proto-Indo-Aryan from Proto-Indo-Iranian but lost around or after the time of the Rigveda, as evidenced due to ḷh (an aspirated retroflex lateral consonant) being metrically a cluster (that was most likely of the form ẓḍh; aspirated fricatives are exceedingly rare in any language). The retroflex consonants are somewhat marginal phonemes, often being conditioned by their phonetic environment; they do not continue a PIE series and are often ascribed by some linguists to the substratal influence of Dravidian or other substrate languages. The nasal [ɲ] is a conditioned allophone of /n/ (/n/ and /ɳ/ are distinct phonemes—aṇu 'minute', 'atomic' [nom. sg. neutr. of an adjective] is distinctive from anu 'after', 'along'; phonologically independent /ŋ/ occurs only marginally, e.g. in prāṅ 'directed forwards/towards' [nom. sg. masc. of an adjective]). There are thus 31 consonantal or semi-vocalic phonemes, consisting of four/five kinds of stops realised both with or without aspiration and both voiced and voiceless, three nasals, four semi-vowels or liquids, and four fricatives, written in IAST transliteration as follows: k, kh, g, gh; c, ch, j, jh; ṭ, ṭh, ḍ, ḍh; t, th, d, dh; p, ph, b, bh; m, n, ṇ; y, r, l, v; ś, ṣ, s, h or a total of 36 unique Sanskrit phonemes altogether.

The phonological rules which are applied when combining morphemes to a word, and when combining words to a sentence, are collectively called sandhi "composition". Texts are written phonetically, with sandhi applied (except for the so-called padapāṭha).

Phonological processes

A number of phonological processes have been described in detail. One of them is abhinidhāna (lit. 'adjacent imposition'), (also known as āsthāpita, 'stoppage', bhakṣya or bhukta). It is the incomplete articulation, or ""repressing or obscuring", of a plosive or, according to some texts, a semi-vowel (except r), which occurs before another plosive or a pause. It was described in the various Prātiśākhyas as well as the Cārāyaṇīya Śikṣa. These texts are not unanimous on the environments that trigger abhinidhana, nor on the precise classes of consonants affected.

One ancient grammarian, Vyāḍi (in Ṛgveda Prātiśākhya 6.12), states that abhinidhāna only occurred when a consonant was doubled, whereas according to the text of the Śākalas it was obligatory in this context but optional for plosives before another plosive of a different place of articulation. The Śākalas and the Atharva Veda Prātiśākhya agree on the observation that abhinidhana occurs only if there is a slight pause between the two consonants and not if they are pronounced jointly. Word-finally, plosives undergo abhinidhāna according to the Atharva Veda Prātiśākhya and the Ṛgveda Prātiśākhya. The latter text adds that final semivowels (excluding r) are also incompletely articulated. The Atharva Veda Prātiśākhya 2.38 lists an exception: a plosive at the end of the word will not undergo abhinidhāna and will be fully released if it is followed by a consonant whose place of articulation is further back in the mouth. The Cārāyaṇīya Śikṣa states that the consonants affected by abhinidhāna are the voiceless unaspirated plosives, the nasal consonants and the semivowels l and v.

According to Siddheshwar Varma, these differences may indicate geographical variation. It is not clear whether abhinidhana was present in the early spoken Sanskrit or it developed at a later stage. In Prakrit and Pāli abhinidhana was carried a step forward into complete assimilation, as for example Sanskrit: sapta to Jain Prakrit: satta.

Syntax

Because of Sanskrit's complex declension system, the word order is free. In usage, there is a strong tendency toward subject–object–verb (SOV), which was the original system in place in Vedic prose. However, there are exceptions when word pairs cannot be transposed.

Peculiar characteristics

In the introduction to his celebrated translation of Vidyakara's 'Subhashitaratnakosha', Daniel H.H. Ingalls describes some peculiar characteristics of the Sanskrit language. He refers to the enormous vocabulary of Sanskrit, and also of the presence of a larger choice of synonyms in Sanskrit than any other language he knew of. Further, he writes, just as there exist a vast number of synonyms for almost any word in Sanskrit, there also exist synonymous constructions. Ingalls writes that in elementary Sanskrit examinations he would ask his students to write in Sanskrit the sentence 'You must fetch the horse' in ten different ways. Actually, Ingalls explains, it is possible to write the sentence in Sanskrit in around fifteen different ways 'by using active or passive constructions, imperative or optative, an auxiliary verb, or any of the three gerundive forms, each of which, by the way, gives a different metrical pattern'. Ingalls emphasizes that while these constructions differ formally, emotionally they are identical and completely interchangeable. He comments that in any natural language this would be impossible. Ingalls uses this and other arguments to show that Sanskrit is not a natural language, but an 'artificial' language. By 'artificial', he explains he means it was learned after some other Indian language had been learned by simple conditioning. Ingalls writes: 'Every Indian, one may suppose, grew up learning naturally the language of his mother and his playmates. Only after this and if he belonged to the priesthood or the nobility or to such a professional caste as that of the clerks, the physicians, or the astrologers would he learn Sanskrit. As a general rule, Sanskrit was not the language of the family. It furnished no subconscious symbols for the impressions which we receive in childhood nor for the emotions which form our character in early adolescence.'
