löysi

löysi is the third-person singular past tense form of the Finnish verb löytää, meaning "to find." It is used to describe that someone found something in the past. The related forms in the past tense are minä löysin (I found), sinä löysit (you found), hän löysi (he/she found), me löysimme (we found), te löysitte (you found), he löysivät (they found). The infinitive is löytää.

Löytyä is a related verb meaning "to be found" or "to turn out to be," but löysi as a finite past-tense form of löytää is active: someone actively found something. In sentences, löysi typically answers “who found what,” and is often accompanied by an object in the accusative or elative case, such as avaimen (the key) or tiedon (the information).

Usage examples:

- Hän löysi avaimen pöydältä. (He found the key on the table.)

- Lapsi löysi kadonneen lelun rakkaan paikan takaa. (The child found the lost toy behind a favorite spot.)

- He löysivät uuden reitin kaupungin halki. (They found a new route across the city.)

Etymology and varieties:

löytä- is a native Finnish verb stem; the exact historical development is complex and discussed among linguists. The form löysi is standard in modern Finnish and appears in all registers, from everyday speech to formal writing.

In summary, löysi is a common, grammatically regular past tense form used to convey a completed act of finding by a subject.
