mitätietäisesti
Mitätietäisesti is a Finnish adverb that translates to "ignorantly," "unknowingly," or "without knowing" in English. It describes an action or state of being done or experienced without awareness or knowledge of certain facts or circumstances. The adverb is formed from the word "mitä," meaning "what," and "tietää," meaning "to know," with the adjectival suffix "-mätön" (meaning "un-" or "without") and the adverbial suffix "-sti." Therefore, its literal construction suggests a state of "not knowing what."
This adverb is used to indicate that a person acted or reacted without having the necessary information.
