imperfectivního

Imperfectivního is a grammatical term used in Czech linguistics to refer to the imperfective aspect (slovesný vid). It is the genitive singular form of the adjective imperfectivní, which describes verbs that belong to the imperfective aspect. The form is commonly seen in expressions such as imperfectivního vidu, meaning “of the imperfective aspect.” This usage situates imperfectivního within descriptive grammar and inflection tables rather than as a standalone lexical item.

The imperfective aspect expresses actions without specifying their completion. It covers ongoing, repeated, habitual, or general actions and contrasts with the perfective (dokonavý) aspect, which emphasizes completion or result. In Czech, verbs are categorized as imperfective or perfective by their base form, prefixes, or periphrastic constructions; many verbs have distinct imperfective and perfective pairs. The choice of aspect affects tense usage and meaning: a present-tense sentence with an imperfective verb describes ongoing action, while a sentence with a perfective verb describes a completed event.

Across Slavic languages, similar aspect distinctions exist. Czech terminology uses imperfectivní for imperfective and dokonavý for perfective to describe these opposed verb forms. The specific form imperfectivního appears in grammatical descriptions and inflectional references rather than as a stand-alone verb. In usage, it is primarily encountered in academic, dictionary, or educational materials about verb aspect.
