osallistunut

Osallistunut is a Finnish past participle derived from the verb osallistua, meaning to participate or take part. In Finnish grammar it functions mainly as an adjective and as part of the perfect tense when used with the auxiliary olla (to have). As a participle, osallistunut denotes a completed participation and can modify a noun or appear in predicate position in clauses that express completed action.

In the perfect tense, it is used with the appropriate form of olla: Hän on osallistunut kilpailuun. This translates to “He/She has participated in the competition.” As an attributive modifier, it can describe a noun to indicate past participation, for example osallistunut henkilö (the person who has participated) or osallistuneet kilpailijat (the participants who have participated). Like other Finnish adjectives and participles, osallistunut inflects for number and case, yielding forms such as osallistuneen (genitive singular) and osallistuneet (nominative plural), among others.

Related forms include osallistua (to participate), osallistuminen (participation), and osallistuja (participant). The related present participle is osallistuva, which describes someone who is currently participating or likely to participate, as in osallistuva henkilö.

Usage notes: osallistunut emphasizes that participation has already occurred, typically in contexts describing past events, achievements, or eligibility based on prior involvement. It is common in formal and written Finnish, as well as in journalistic and bureaucratic prose, to convey a completed participation without ambiguity.
