käituva
Käituva is a term that appears infrequently in Finnish, and it is not established as a standard lexical entry in major dictionaries. In contemporary Finnish, present active participles are typically formed with the suffixes -vä or -va (for example, kävelevä from kävellä, or käyttävä from käyttää). The form käituva does not correspond to a widely recognized, productive participle in standard Finnish grammar, and it is not listed as a separate word with a fixed meaning in reputable references.
Because käituva is not attested as a standard form, its presence in texts is usually considered uncertain
If the intention is to convey a sense related to behaving or conduct, standard Finnish alternatives are
See also: käyttäytyä, käyttävä, käytyä, kävely (as contextual points for related stems and common participles).
