ostettiin

Ostettiin is a Finnish verb form that represents the passive past tense of the verb ostaa, meaning to buy. It translates to was bought or were bought in English and is used to indicate that something has been purchased, with the doer of the purchase left unspecified.

Grammatically, ostettiin is the finite passive form used for past actions. In Finnish, the passive voice does not require an explicit subject, and the agent performing the purchase is often omitted. The form ostettiin does not vary for number; it can describe a single item or multiple items depending on the subject of the sentence. It contrasts with the active past tense, where the subject performs the action (e.g., ostin, ostit, osti, ostimme, ostitte, ostivat).

Usage notes: Ostettiin is common in news reports, official statements, advertisements, and everyday language when the focus is on the fact that a purchase occurred rather than on who made it. It can be paired with time adverbs such as eilen (yesterday) or viime viikolla (last week) to situate the event in time. The related past participle ostettu can function as an adjective or participle, meaning bought, as in ostettu auto (a bought car) or ostettu tuote (the bought product). The form is part of the broader Finnish system of passive conjugations that allows conveying completed actions without naming agents.

Examples:

- Auto ostettiin eilen. The car was bought yesterday.

- Monet tavarat ostettiin joululahjoiksi. Many items were bought as Christmas gifts.

- Ruoat ostettiin kaupasta. The foods were bought from the store.
