This form is typically used in sentences that describe an action or state that is dependent on a certain condition.

The conditional conjugation in Finnish involves adding the suffix "-isi" or "-isi" to the verb stem, with the exact form depending on vowel harmony. For "käyttäytyä," the stem is "käyttäyty-" and the conditional suffix is "-isi," resulting in "käyttäytyisi." This grammatical form is essential for conveying nuanced meanings related to possibility, desire, and politeness in the Finnish language.
