Vedic Sanskrit grammar

Vedic Sanskrit is the Indo-Aryan language used in the religious hymns known as the Vedas, composed from the early-to-mid 2nd millennium through to the mid 1st millennium, BCE. It was a spoken language during that period. Its grammar differs in certain respects from the grammar of the later Classical Sanskrit.

Differences from Classical Sanskrit

Compared with Classical Sanskrit, Vedic had a subjunctive mood absent in Pāṇini's grammar and generally believed to have disappeared by then at least in common sentence constructions. All tenses could be conjugated in the subjunctive and optative moods, in contrast to Classical Sanskrit, with no subjunctive and only a present optative. However, the old first-person subjunctive forms were used to complete the Classical Sanskrit imperative. The three synthetic past tenses (imperfect, perfect and aorist) were still clearly distinguished semantically in (at least the earliest) Vedic. A fifth mood, the injunctive, also existed.

Long-i stems differentiate the Devi and Vrkis feminines, a difference lost in Classical Sanskrit.

• The subjunctive mood of Vedic was also lost in Classical Sanskrit. Also, there was no fixed rule about the use of various tenses (luṇ, laṇ and liṭ).
• There were more than 12 ways of forming infinitives in Vedic, of which Classical Sanskrit retained only one form.
• Nominal declinations and verbal conjugation also changed pronunciation, although the spelling was mostly retained in Classical Sanskrit. E.g., along with the Classical Sanskrit's declension of deva- as devaḥ—devau—devāḥ, Vedic additionally allowed the forms daivaḥ—daivā—daivāsaḥ. Similarly Vedic has declined forms such as asmai, tvai, yuṣmai, tvā, etc. for the first and second person pronouns, not found in Classical Sanskrit. The obvious reason is the attempt of Classical Sanskrit to regularize and standardize its grammar, which simultaneously led to a purge of older Proto-Indo-European forms.
• To emphasize that Proto-Indo-European and its immediate daughters were essentially end-inflected languages, both Proto-Indo-European and Vedic had independent prefix-morphemes. Such prefixes (especially for verbs) could come anywhere in the sentence, but in Classical Sanskrit, it became mandatory to attach them immediately before the verb.

Morphology

Nouns

Vedic is a highly inflected language with three grammatical genders (masculine, feminine, neuter) and three numbers (singular, plural, dual). It has eight cases: nominative, vocative, accusative, instrumental, dative, ablative, genitive, and locative.

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

The basic declension suffix scheme for nouns and adjectives

The basic scheme 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.[1]

	Singular	Dual	Plural
Nominative	-ः (-Ø) -ḥ (-Ø)	-ौ (-ी) -āu (-ī)	-ाः (-ि) -aḥ (-i)
Vocative	-Ø
Accusative	-म (-Ø) -m (-Ø)
Instrumental	-ा -ā	-भ्याम् -bhyām	-भिः -bhiḥ
Dative	-े -ai		-भयः -bhyaḥ
Ablative	-ः -aḥ
Genitive		-ोः -auḥ	-ाम् -ām
Locative	-ि -i	-ोः -auḥ	-सु -su

a-stems

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

Compounds

One other notable feature of the nominal system is the very common use of nominal compounds, which may be huge (10+ words) as in some modern languages such as German. 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. Some examples of nominal compounds include:

Dvandva द्वन्द्व​ (co-ordinative)

These consist of two or more noun stems, connected in sense with 'and'. There are mainly two kinds of dvandva द्वन्द्व​ constructions in Sanskrit. The first is called itaraitara dvandva इतरेतर द्वन्द्व, an enumerative compound word, the meaning of which refers to all its constituent members. The resultant compound word is in the dual or plural number and takes the gender of the final member in the compound construction. e.g. rāma-lakṣmaṇāu रामलक्ष्मणौ – Rama and Lakshmana, or rāma-lakṣmaṇa-bharata-śatrughnāh रामलक्ष्मणभरतशत्रुघ्नाह् – Rama, Lakshmana, Bharata and Satrughna. The second kind is called samāhāra dvandva समाहार द्वन्द्व​, a collective compound word, the meaning of which refers to the collection of its constituent members. The resultant compound word is in the singular number and is always neuter in gender. e.g. pāṇipādam पाणिपादम् – limbs, literally hands and feet, from pāṇi पाणि 'hand' and pāda पाद​ 'foot'. According to some grammarians, there is a third kind of dvandva, called aikaśaiṣa dvandva एकशेष द्वन्द्व or residual compound, which takes the dual (or plural) form of only its final constituent member, e.g. pitarau for mātā + pitā, mother + father, i.e. parents. According to other grammarians, however, the aikaśaiṣa एकशेष is not properly a compound at all.

Bahuvrīhi बहुव्रीहि (possessive)

Bahuvrīhi बहुव्रीहि, or "much-rice", denotes a rich person—one who has much rice. Bahuvrīhi compounds refer (by example) to a compound noun with no head -- a compound noun that refers to a thing which is itself not part of the compound. For example, "low-life" and "block-head" are bahuvrihi compounds, since a low-life is not a kind of life, and a block-head is not a kind of head. (And a much-rice is not a kind of rice.) Compare with more common, headed, compound nouns like "fly-ball" (a kind of ball) or "alley cat" (a kind of cat). Bahurvrīhis can often be translated by "possessing..." or "-ed"; for example, "possessing much rice", or "much riced".

Tatpuruṣa तत्पुरुष (determinative)

There are many tatpuruṣas (one for each of the nominal cases, and a few others besides); 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. It would be called a "caturthitatpuruṣa" चतुर्थितत्पुरुष​ (caturthi चतुर्थि refers to the fourth case—that is, the dative). Incidentally, "tatpuruṣa" is a tatpuruṣa तत्पुरुष ("his man"—meaning someone's agent), while "caturthitatpuruṣa" चतुर्थितत्पुरुष is a karmadhārya, being both dative, and a tatpuruṣa. An easy way to understand it is to look at English examples of tatpuruṣas: "battlefield", where there is a genitive relationship between "field" and "battle", "a field of battle"; other examples include instrumental relationships ("thunderstruck") and locative relationships ("towndwelling").

Karmadhāraya कर्मधारय​ (descriptive)

The relation of the first member to the last is appositional, attributive or adverbial, e. g. uluka-yatu उलुकयतु (owl+demon) is a demon in the shape of an owl.

Amraiḍita अम्रेडित​ (iterative)

Repetition of a word expresses repetitiveness, e. g. dinai dinai दिनेदिने 'day by day', 'day after day', 'daily'.

Dvigu द्विगु

Dvigu is a subtype of tatpuruṣa in which the modifying member is a number. Dvigu (lit., "[a] two-cow [person]"; i.e., one who has two cows) itself is a compound : द्वो+गवौ dvau+gāvau.

Personal pronouns and determiners

The first and second person pronouns are declined for the most part alike, having by analogy assimilated themselves with one another.

Note: Where two forms are given, the second is enclitic and an alternative form. Ablatives in singular and plural may be extended by the syllable -tas; thus mat or mattas, asmat or asmattas.

Classification of verbs

Sanskrit has ten classes of verbs divided into two broad groups: athematic and thematic. 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.

Grades

Vowel (zero) grade	a, -	i, ī	u, ū	ṛ, ṝ	ḷ
Short diphthong (Guṇa) grade	a, ai	ai	au	ar	al

The verbs 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, the imperfect, and 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.

For thematic verbs, the present tense stem may be formed through:

• 1. Suffixation of the thematic vowel a with guṇa strengthening, for example, bháva- from bhū 'be', bhara- from bhṛ (guṇa form bhar-) 'bring'.
• 6. Suffixation of the thematic vowel a with a shift of accent to this vowel, for example tudá- from tud 'thrust'.
• 4. Suffixation of ya, for example dī́ vya- from div 'play', paśya- from pś 'see'.

For athematic verbs, the present tense stem may be formed through:

• 2. No modification at all, for example ad- from ad 'eat'.
• 3. Reduplication prefixed to the root, for example juhu- from hu 'sacrifice', dadhā- from dhā 'put'.
• 7. Infixion of ná or n before the final root consonant (with appropriate sandhi changes), for example rundh- or ruṇadh- from rudh 'obstruct', yunaj- from yuj 'join' (yunakti 'he joins').
• 5. Suffixation of nu (guṇa form náu), for example sunu- from su 'press out', stṛnau- from stṛ 'strew' (stṛnumas 'we strew', stṛnvanti 'they strew').
• 8. Suffixation of u (guṇa form au), for example tanu- from tan 'stretch'. For modern linguistic purposes it is better treated as a subclass of the 5th. tanu- derives from tnnu-, which is zero-grade for *tannu-, because in the Proto-Indo-European language [m] and [n] could be vowels (i.e. [am], [an]), which in Sanskrit (and Greek) change to [a]. Most members of the 8th class arose this way; kar- 'make, do' was 5th class in Vedic (krnauti 'he makes'), but shifted to the 8th class in Classical Sanskrit (karauti 'he makes')
• 9. Suffixation of nā (zero-grade nī or n), for example krīṇa- or krīṇī- from krī 'buy', pūna- from pū 'clean'.
• 10. This class described by native grammarians refers to a process which is derivational in nature, and thus not a true tense-stem formation. It is formed by suffixation of ya with guṇa or vṛddhi strengthening and lengthening of the root's last vowel, for example bhāvaya- (< bāu-a-ya-) from bhū 'be', pūjaya- from pūj 'honour', cauraya- from cur (guṇa form caur-) 'steal', dāvaya- from du (vṛddhi form dāv-) 'burn'.

The present system also differentiates strong and weak forms of the verb. The strong/weak opposition manifests itself differently depending on the class:

• The root and reduplicating classes (2 & 3) are not modified in the weak forms, and receive guṇa in the strong forms.
• The nasal class (7) is not modified in the weak form, extends the nasal to ná in the strong form.
• The nu-class (5) has nu in the weak form and náu in the strong form.
• The nā-class (9) has nī in the weak form and nā́ in the strong form. nī disappears before vocalic endings.

Perfect system

The perfect is used mainly in the indicative. 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.

The perfect in the Sanskrit can be in form of the simple perfect and the periphrastic perfect.

The Simple Perfect can form an augmented Pluperfect, and beyond the indicative mood it can also form Perfect Subjunctives, Optatives, and Imperatives. All of these are lost in Classical Sanskrit, when it forms only indicatives.

The simple perfect is the most common form and can be made from most of the roots. The simple perfect stem is made by reduplication and if necessary by stem lengthening. The conjugated form takes special perfect endings. The periphrastic perfect is used with causative, desiderative, denominative and roots with prosodic long anlauted vowel (except a/ā). Only few roots can form both the simple and the periphrastic perfect. These are bhṛ 'carry', uṣ 'burn', vid 'know', bhi 'to be afraid', hu 'sacrifice'.

Aorist system

The aorist system includes aorist proper (with past indicative meaning, e.g. abhūs 'you were') and some of the forms of the ancient injunctive (used almost exclusively with mā in prohibitions, e.g. mā bhūs '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 reduplicating aorist (semantically related to the causative verb), and the sibilant aorist. The simple aorist is taken directly from the root stem (e.g. bhū-: a-bhū-t 'he was'). The reduplicating aorist involves reduplication as well as vowel reduction of the stem. The sibilant aorist is formed with the suffixation of s to the stem. The sibilant aorist by itself has four formations:

• athematic s-aorist
• athematic iṣ-aorist
• athematic siṣ-aorist
• thematic s-aorist

Future system

The future system is formed with the suffixation of -sya- or -iṣya- and guṇa, both in the simple future and conditional. There exists also so called periphrastic future, which is made by adding suffix tṝ to the stem and the short as 'to be' form.

Conjugation

Each verb has a grammatical voice, whether active, passive or middle. There is also 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 Vedic 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.

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

In present and imperfect indicative singular active forms have the accent on the stem and take strong forms, while the other forms have the accent on the endings and take weak forms.

In imperative accent is variable and affects vowel quality. Forms which are end-accented trigger guṇa strengthening, and those with stem accent do not have the vowel affected.

The Passive voice forms for all tenses and moods are made by adding -ya- to the zero-grade stem and then adding the middle voice ending of appropriate tense and mood.

The Causative is made by adding the suffix aya to the vṛddhi form. For example, karauti 'he does/makes', and kārayati 'he lets do/make'.

The Desiderative is made by reduplication of the root and the suffix sa. For example, karauti 'he does, makes', and cikīrṣati 'he wishes to do/make'. It can be also combined with causative, e.g. kārayati 'he lets do' and cikārayiṣati 'he wishes to let to do'.

The Intensive (or sometimes called Frequentative) describes a repeated or particularly intensive activity. With verbs of the movement it means "back and forth". The intensive is formed by reduplication of the root and the suffix ya with middle endings for thematic stems, and without suffix and active endings for athematic stems. For example, bhramati 'it curves around', and baṃbhramyatai 'it curves cross and crosswise around'.

Syntax

Because of Vedic's complex declension system the word order is free (with tendency toward SOV).
