poistui

Poistui is a Finnish verb that functions as the past tense form of poistua. Poistua is an intransitive verb meaning to leave a place, depart, or disappear from view. Because it is intransitive, it does not take a direct object; the subject is the one performing the departure or disappearance.

Poistui is the third-person singular imperfect form. Other forms of poistua include minä poistuin (I left), sinä poistuit (you left), hän poistui (he/she left), me poistuimme, te poistuitte, he poistuivat. The present tense is poistuu, and the past participle is poistunut, used in perfect constructions like hän on poistunut. A related noun is poistuminen, referring to departure or disappearance, while poisto can denote removal or deletion in other contexts.

In usage, poistui commonly describes someone departing from a location or retreating from a scene, and it can also describe something disappearing from view. Examples: Hän poistui ovelta. (He left through the door.) Kuva poistui näkyvistä. (The image disappeared from sight.) Lääkäri poistui paikalta tapahtuman päätyttyä. (The doctor left the scene after the event ended.)

Poistua can be extended to phrases such as poistua paikalta or poistua näkyvistä to indicate leaving or disappearing from a place or from view. The form poistui is common in written and spoken Finnish, especially in narrative and reporting styles.
