such as (માં (mā̃), થી (thī), નું (nũ), etc.), they are attached to the oblique forms ક્યાર (kyār), કેટલા (keṭlā), કેવડા (kevṛā), કેવા (kevā), etc. resulting in ક્યારથી (kyārthī), કેટલામાં (keṭlāmā̃), etc. Verbs Overview The Gujarati verbal system is largely structured around a combination of aspect and tense/mood. Like the nominal system, the Gujarati verb involves successive layers of (inflectional) elements after the lexical base. Gujarati has 2 aspects: perfective and imperfective, each having overt morphological correlates. These are participle forms, inflecting for gender, number, and case by way of a vowel termination, like adjectives. The perfective forms from the verb stem, followed by -ય(y)-, capped off by the agreement vowel and the imperfective forms with -ત(t)-. Derived from હોવું (hɔvũ) "to be" are five copula forms: present, subjunctive, past, contrafactual (aka "past conditional"), and presumptive. Used both in basic predicative/existential sentences and as verbal auxiliaries to aspectual forms, these constitute the basis of tense and mood. Non-aspectual forms include the infinitive, the imperative, and the agentive. Mentioned morphological conditions such the subjunctive, contrafactual, etc. are applicable to both copula roots for auxiliary usage with aspectual forms and to non-copula roots directly for often unspecified (non-aspectual) finite forms. Finite verbal agreement is with the nominative subject, except in the transitive perfective, where it is with the direct object, with the erstwhile subject taking the ergative construction -એ(e) (see postpositions above). The perfective aspect thus displays split ergativity. The infinitive's agreement is also with its direct object, if paired with one. Tabled just below on the left are the paradigms for the major gender and number agreement termination (GN), nominative case. Oblique paradigms differ from those introduced in #Nouns, being either thoroughly -આ(ā) or આં(ā̃). Locative -એ(e) is found in attributive adjectival function only in fixed expressions. To the right are the paradigms for the person and number agreement termination (PN), used by the subjunctive and future. Yellow fields: -એ (e) following C, ઉ (u), ઊ (ū); -ઈ (ī) following ઓ (o), ઓ (ɔ); -ય (y) following આ (ā). Forms The example verb is intransitive hālvũ "to shake", with various sample inflections. Much of the below chart information derives from . Notes The negation particles are na and nahi with the former standing before the copula (or if no copula, the aspectual form) and the latter generally after. A negation particle combines with present ch-PN however for the invariable nathī. An
