ttivät
"ttivät" is a Finnish word, a past tense plural form of the verb "tietää." "Tietää" means "to know" in English. Therefore, "ttivät" translates to "they knew." This verb conjugation indicates that a group of people possessed knowledge or information about something in the past. The word itself is not a noun or a standalone concept but a grammatical form used within sentences to describe a past action of knowing performed by multiple subjects. For example, in a sentence like "He and his friends ttivät the answer," it means "He and his friends knew the answer." The specific context of the sentence would further clarify what it is that "they knew." The Finnish language has a rich system of verb conjugations, and "ttivät" is one example of how past tense and plural subject agreement are marked.
