Basics Verb conjugation in Sanskrit involves the interplay of number, person, voice, mood and tense, with the following variables: Further,
participles are considered part of the verbal systems although they are not verbs themselves, and as with other Sanskrit nouns, they can be declined across seven or eight
cases, for three
genders and three numbers. As many as a dozen types of infinitives can be found in Vedic, although only a couple of types are frequent.
Building blocks Stem formation The starting point for conjugation is the
root. As a first step, the root may be subject to treatment to form a stem, to which personal endings are suffixed. The types of possible treatment are: • Suffixion: the
theme vowel -a- may be appended, or one of several other suffixes
-ya-,
-ó- / -nó-,
-nā-, and
-aya-. • Infixion: A nasal infix (
n,
ñ,
ṇ,
ṅ) may be inserted within the root, which when accented is
-ná-. • The root may undergo
reduplication. • In some tenses or moods, the augment
á- may be prefixed. • In many cases, the accent may vary between the root and the ending, accompanied by corresponding changes in the gradation of the root vowel. If V is the vowel of the zero grade, the -grade vowel is traditionally thought of as a + V, and the -grade vowel as ā + V.
Personal 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. The primary, secondary, perfect and imperative endings are essentially the same as seen in Classic Sanskrit. The subjunctive endings can be seen below: 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. There are additional 'a' inserted between the root and the ending, often causing an elongation with a root class' other suffux (bhū (bhav) + a + a + ti = bhavāti).
Conjugation Present system The present system includes the
present tense, the
imperfect, and the
optative,
imperative and
subjunctive moods, and well as rare occurrences of injunctive. The present system conjugations are generally homogeneous with that Classical Sanskrit, see
there.
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 (which is equivalent in value to the imperfect), and beyond the indicative mood it can also form Perfect Subjunctives, Optatives, and Imperatives. All of these are lost in Classical Sanskrit, which 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 '''' 'carry', '''' 'burn', '''' 'know', '''' 'to be afraid', '''' 'sacrifice'.
Aorist system The
aorist system includes aorist proper (with a proximal perfect past indicative meaning, e.g.
akārṣīḥ 'you have done' or 'you did (just now)') 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 also had subjunctive, imperative, and optative forms. Of these, only the optative was preserved in Classical, forming the benedictive (also called the precative) mood. 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 -aorist • athematic -aorist • thematic s-aorist
Future system The s-future is formed with the inffixion of
-syá- or ''
before the normal present endings and . It is generally the more common, with the indication of a simple future. The periphrastic future is formed with the suffix of tṛ́
added directly to the root with guṇa
. In the third person, it is conjugated like a noun ending in ṛ
; the other forms use the nominal form periphrasticly and add the corresponding as'' forms. It is used to refer to a task that will be completed at a specific time in the future. The s-future also contains a preterite formation using the same endings as the imperfect, while also using the
-syá- or '''' infix. This future preterite is used for conditional sentences and clauses. Other than this, Vedic had a small scattering of imperative and optative future forms. However, they were completely phased out as the language continued to evolve.
Examples of conjugation Comprehensive conjugation tables can be found in the Classical Sanskrit page linked above. Some notes on elements specific to Vedic Sanskrit below: ;
bhū – 'to be' The optative takes secondary endings.
-ya- is added to the stem both in the active and the middle. In some forms the cluster
ya is dropped out. The subjunctive takes subjunctive endings. The following stems can take all endings. ;
