tekevätkö

"tekevätkö" is a Finnish interrogative verb form. It is the third-person plural present tense of the verb "tehdä" (to do/to make), combined with the interrogative particle "-kö". This particle is attached to the verb to form a question. Therefore, "tekevätkö" directly translates to "do they do?" or "are they doing?". It is used when asking a question about the actions of a group of people or things in the present tense. For example, "tekevätkö he työtä?" means "are they working?". The "-kö" suffix is a common way to form questions in Finnish, and it is appended to the verb, pronoun, or other word that is emphasized in the question. In this case, the emphasis is on the action performed by the plural subject. The absence of the "-kö" suffix, "tekevät", would form a statement, meaning "they do" or "they are doing". The grammatical structure of Finnish often involves suffixes to indicate tense, person, and mood, and the interrogative particle is a key element in forming questions.
