äänilliseen

The Finnish word "äänilliseen" is the genitive singular form of "äänillinen". "Äänillinen" is an adjective meaning "vocal" or "audible". It is derived from the noun "ääni", which means "sound" or "voice".

The genitive case in Finnish is used to express possession, origin, or to be the object of certain prepositions and postpositions.
