Koostin

Koostin is an Estonian verb form derived from the verb koostama, which means to compose, assemble, or put together. It is used to indicate that the speaker performed the action of composing or assembling something. In Estonian, verbs are inflected for person and tense, and koostin appears in contexts describing actions carried out by the speaker, typically in the past.

The base verb, koostama, belongs to a common class of Estonian verbs that describe creating or organizing material, information, or objects. Related forms include the noun koostamine, referring to the act of composing or assembling, and other inflected forms used for different subjects and tenses. Koostin can occur in narratives or descriptions where the speaker is recounting what they have put together, whether a written text, a list, a plan, or other compilations.

Usage notes:

- Koostin is most often encountered in past-tense constructions with the first-person singular subject.

- In present-tense storytelling or description, other forms of the same verb would be used (for example, a present-tense form of koostama appropriate to the subject).
