ääniäänensä

Ääniäänensä is a Finnish word that is an example of a possessive suffix. It literally translates to "his/her/its own voice". This construction is formed by combining the noun "ääni" (voice) with the possessive suffix "-nsä". The "-nsä" suffix indicates a third-person possessor, meaning it refers to someone or something belonging to "him," "her," or "it." The doubling of the "ääni" is a grammatical feature in Finnish that occurs in certain possessive constructions to distinguish them from other grammatical forms and to emphasize the possessive nature. Therefore, "ääniäänensä" specifically refers to the voice belonging to the subject of the sentence, and it is a reflexive possessive, meaning the possessor is the same as the subject. For instance, in the sentence "Hän kuunteli ääniäänensä," which means "He/She listened to his/her own voice," the "-nsä" clearly links the voice back to the subject "hän." This grammatical phenomenon is common in Finnish and helps to convey nuanced meaning about possession and reference within a sentence.
