avannut

Avannut is the Finnish past active participle of the verb avata, meaning "to open." It denotes a completed opening action and is used primarily in perfect tense constructions with the auxiliary olla, for example Olen avannut ikkunan ("I have opened the window") and Olemme avanneet ovet ("we have opened the doors").

In Finnish, past active participles are not declined for person or number; the subject is expressed through the auxiliary verb. The singular form avannut is used with singular subjects, while the plural form avanneet is used with plural subjects in compound perfects: Olemme avanneet ovet.

Formation and usage: avata + -nut yields the past active participle. The form avannut is the singular past participle, and avanneet is the plural past participle. The participle functions as a non-finite verb form within compound tenses and can be used to convey that an opening action has been completed relative to another time reference.

Etymology: Avannut is derived from the verb avata with the suffix -nut, a standard pattern for Finnish past active participles.
