käändluste
Kääntluste is a term originating from Estonian linguistics, referring to the process of grammatical inflection, specifically declension and conjugation. In essence, it describes how words change their form to indicate grammatical function, such as case, number, tense, or person. Estonian is a highly inflected language, meaning that kääntluste plays a significant role in its grammatical structure. Nouns, pronouns, adjectives, and participles undergo declension, changing their endings to show their role in a sentence, such as subject, object, or possessor. Verbs undergo conjugation, altering their forms to reflect tense (past, present, future), mood (indicative, imperative, conditional), and person (first, second, third) and number (singular, plural). Understanding kääntluste is crucial for comprehending and constructing grammatically correct Estonian sentences. The system of kääntluste in Estonian, while complex, allows for a high degree of grammatical information to be conveyed through word endings, often reducing the need for prepositions or auxiliary verbs found in other languages.
