tysivätkö

"tysivätkö" is a Finnish word that functions as a past tense interrogative form of the verb "tysätä". The verb "tysätä" itself generally means to fail, to flop, to collapse, or to come to nothing. Therefore, "tysivätkö" is used to ask whether something (plural or referring to a group) failed, flopped, collapsed, or came to nothing in the past.

The grammatical structure of "tysivätkö" involves the past tense stem of the verb "tysätä", which is "tysäi-", followed by the third-person plural past tense ending "-vät". The interrogative particle "-kö" is then suffixed to the verb to form the question. This grammatical construction is typical for forming questions in Finnish.

For example, in a sentence, "Tysivätkö heidän suunnitelmansa?" translates to "Did their plans fail?". Here, "suunnitelmansa" (their plans) is plural, and "tysivätkö" correctly agrees with it. The word can be used in various contexts, from discussing the success of a project to the outcome of an event. Understanding the base verb "tysätä" is key to comprehending the meaning of "tysivätkö" and its various applications in Finnish conversation and writing.
