Ustanovili

Ustanovili is a past tense verb form used in several South Slavic languages, notably Serbian, Croatian, and Bosnian. It is the masculine plural form of the perfective verb ustanoviti, meaning to establish, set up, or install. Because ustanoviti is perfective, the past tense form marks a completed action.

In these languages, past-tense forms agree with the subject in gender and number. Thus, ustanovili corresponds to a masculine plural subject (they established or they installed). The feminine plural form is ustanovile, the singular masculine form is ustanovio, the singular feminine form is ustanovila, and the neuter singular form is ustanovilo. Usage in a sentence typically places the auxiliary verb su before the participle, for example: Oni su ustanovili novu politiku. Alternatively, the verb can appear without explicit subject pronouns: Ustanovili su novu politiku.

Ustanovili can denote founding an institution, adopting a policy, or installing equipment, depending on context. It is common in news reporting, government statements, and formal writing.

Related forms include the infinitive ustanoviti, and the noun ustanova (institution) related in meaning. The term shares cognates across Slavic languages and appears in various texts to convey the completion of a founding or installation action.
