täyttyivät

Täyttyivät is the plural imperfect form of the Finnish verb täyttyä, meaning “to become full” or “to fill up.” It is used to describe a state change where a space, capacity, or amount has reached its limit or has become occupied. The form is appropriate when the subject is plural.

Grammatically, täyttyivät expresses past action or a past state in the indicative mood for third-person plural. The verb täyttyä is intransitive, so the subject of täyttyivät is what becomes full, rather than something that fills it. The stem is täytty-, and the past plural ending is -ivät. This form contrasts with täyttyy (present tense, singular or plural depending on subject) or with the transitive verb täyttää, which means “to fill (something).”

Common usage describes scenarios where capacity or availability is exhausted or occupied. For example, in event reporting one might say kokouksen paikat täyttyivät nopeasti, meaning that the seats for the meeting filled up quickly. Another example could reference calendars or spaces becoming full as bookings or attendees accumulate.

Related forms include täyttyä (to become full), täyttyminen (the state or act of becoming full), and related phrases describing capacity or occupancy. The term should not be confused with täyttää, a transitive verb meaning “to fill (something)” which functions differently in sentence structure and meaning.

In summary, täyttyivät denotes that multiple subjects became full in the past, commonly used for crowds, spaces, or capacities reaching their limit.
