järjestivät

Järjestivät is the third-person plural past tense form of the Finnish verb järjestää, meaning to organize, arrange, or conduct. It denotes that a group performed an organizing action in the past. The infinitive form is järjestää, and in this past-tense construction the verb takes the ending -ivät to indicate a completed action by multiple subjects.

The form is commonly used in narratives, reports, and everyday speech to describe events or activities organized by several people or groups. Examples include: He järjestivät tilaisuuden eilen. (They organized the event yesterday.) Koulun vanhemmat järjestivät juhlan. (The school’s parents organized the celebration.) In each case, järjestivät attributes responsibility for arranging something to a plural subject in the past.

Notes on usage and related forms: Finnish verbs are highly inflected for person and number. Järjestöt, järjestät, and järjestän are other forms of the same verb paradigm, corresponding to different persons and tenses (for example, minä järjestän = I organize, sinä järjestät = you organize). The infinitive remains järjestää, while järjestivät specifically marks past tense with a plural subject.
