Käyttäytyvätkin

Käyttäytyvätkin is a Finnish word that functions as an adverb. It is the plural form of the adverb "käyttäytyvä" and carries the meaning of "behaving too" or "also behaving." The word implies a comparison or an addition to a previously mentioned behavior. It suggests that a certain action or manner of conduct is occurring in addition to something else, or that even a subject that might not typically be expected to behave in a particular way is, in fact, doing so.

The word is formed by combining the stem of the verb "käyttäytyä" (to behave) with the plural suffix "-vät" and the clitic particle "-kin" (also, too). The particle "-kin" is attached to the end of the word and indicates emphasis or addition. Therefore, "käyttäytyvätkin" can be understood as "they too are behaving" or "even they are behaving." The context in which the word is used determines the precise nuance of its meaning. It is often employed in colloquial speech and informal writing to convey a sense of surprise or observation about a collective or a group's actions.
