käytettiinkö

Käytettiinkö is a Finnish word that functions as a past passive interrogative form. It translates most directly to "was it used?" or "were they used?". The root of the word is the verb "käyttää," meaning "to use." The "-ttiin" ending signifies the passive voice in the past tense, indicating that an action was performed on the subject. The "-kö" ending converts the statement into a question.

Therefore, "käytettiinkö" is used when inquiring about whether something was utilized or employed in the past. For example, a sentence might be "Käytettiinkö tätä työkalua aiemmin?" which translates to "Was this tool used previously?". The grammatical structure implies that the subject of the sentence (e.g., "this tool") was acted upon, rather than performing an action itself. This form is common in spoken and written Finnish when seeking information about past usage.
