Napuniti

Napuniti is a verb used in Croatian, Bosnian, Serbian, and Montenegrin to express the action of making something full or loaded. It is commonly used in contexts such as charging a device or filling a container, for example napuniti bateriju (to recharge a battery), napuniti čašu vodom (to fill a glass with water), or napuniti spremnik (to fill a tank).

Etymology and usage notes: The verb is formed with the prefix na- attached to the root pun-, meaning “full.” Napuniti is generally treated as a perfective verb, indicating completion of the filling action. Its imperfective counterpart is typically expressed by related forms such as napunjivati or, in some contexts, puniti, depending on regional usage and the specific meaning (repeated filling versus a single, completed fill).

Conjugation and examples: In the present tense, forms include ja napunim, ti napuniš, on/ona/ono napuni, mi napunimo, vi napunite, oni/one napune. The past tense uses a participial form with an auxiliary, for example napunio sam bateriju (I charged the battery, masculine), napunila je vodu (she filled the water), napunili smo spremnik (we filled the tank). The future is expressed as ja ću napuniti, ti ćeš napuniti, on/ona/ono će napuniti, mi ćemo napuniti, vi ćete napuniti, oni/one će napuniti.

See also: Related forms and cognates in Slavic languages include the Slovenian napolniti, reflecting a common meaning and shared linguistic heritage. Napuniti remains a standard term for charging or filling in everyday and technical contexts.
