Plnit

Plnit is a verb used in Czech and Slovak to denote filling, loading, stocking, or fulfilling. In Czech, plnit is imperfective, with the perfective counterpart naplnit, which expresses filling something to capacity or fulfilling a goal. It forms with prefixes such as doplnit (to supplement or complete a fill) and vyplnit (to fill out). Present tense forms include plním, plníš, plní; plníme, plníte, plní. Past tense forms are plnil, plnila, plnilo, and the imperative forms are plň and plňte. The noun plnění denotes the act or result of filling, such as plnění nádrže (filling a tank) or plnění povinností (fulfillment of obligations).

In Slovak, plniť serves a similar function, with the perfective naplniť and related prefixed forms. The noun plnenie corresponds to the Czech plnění and likewise means fulfillment or completion. Like its Czech counterpart, Slovak uses a typical Slavic aspect system, with imperfective and perfective pairs and prefixes to shift meaning.

Common usage spans manufacturing, logistics, and data handling, as well as abstract domains such as obligations or goals. Examples include plniť zásoby (to stock/fill supplies), vyplniť formulár (to fill out a form), and plniť si povinnosti (to fulfill one’s duties). In English-language contexts, plnit is usually discussed as a Slavic verb rather than as an English term, though it may appear in linguistic descriptions or as a proper name in certain cases.
