koosolekusse

Koosolekusse is the illative case form of the Estonian noun koosolek, meaning “to the meeting” or “into the meeting.” It is used to express movement toward or entry into a meeting or gathering.

In usage, koosolekusse is typically used with verbs of motion, such as minema (to go), sisenema (to enter), or jõudma (to reach). Example sentences include: Ta läks koosolekusse. Me peame koosolekusse minema. Kas sa lähed koosolekusse?

A koosolek is a formal gathering, such as a council meeting, board meeting, or club meeting. The illative contrasts with the inessive koosolekul (at the meeting) and other location forms to indicate direction rather than location. For example, Ta läks koosolekusse means “He went to the meeting,” while Ta on koosolekul means “He is at the meeting.”

The form is part of the Estonian case system, used to express movement into a location. The illative singular is koosolekusse; plural forms are formed in a similar way from the plural stem. In practice, koosolekusse appears in formal and everyday contexts whenever indicating going to participate in or enter a meeting.
