trvá
Trvá is a Czech verb form meaning "to last" or "to take (time)." It is the present tense, third-person singular form of the verb trvat, which is intransitive and imperfective. The verb describes duration or persistence of a state, event, or process, without implying completion. Because trvat is imperfective, it emphasizes ongoing action rather than a defined endpoint by itself.
Common uses include describing how long something takes or lasts, with durations expressed in numbers and time

Etymology: trvat comes from Proto-Slavic, with cognates in other Slavic languages, e.g., Polish trwać and Ukrainian тривати.
