koosseisus

Koosseisus is an Estonian term used to describe the people or components that currently form a particular group or ensemble. It is commonly applied to sports teams, performing arts casts, film crews, and organizational bodies to indicate the active lineup or composition at a given time.

In sports and competitions, koosseisus refers to the roster or starting lineup available for a match or event. For example, a football team’s koosseisus might include 11 players on the field. In the performing arts and film, the term denotes the cast or ensemble taking part in a production, such as the film’s koosseisus comprising the lead actors and supporting players.

Etymologically, koosseisus is derived from koos- meaning together and seis/ seisus relating to standing or being in a position, forming a noun that conveys the idea of a group assembled for a purpose. The form koosseisus specifically marks a locational or situational state, as in “in the lineup” or “in the ensemble.”

The term is widely used in Estonian-language discourse across sports, arts, and organizational contexts to describe the current composition of a group. Related terms include koosseis (lineup or lineup of a group) and koosseside usage in institutional or governmental contexts.
