Sentence theory is an essential component of Azerbaijani grammar. It deals with the structure and organization of sentences in the Azerbaijani language. In Azerbaijani grammar, a sentence is defined as a group of words that expresses a complete thought or idea.

Sentence theory provides a framework for understanding how sentences are formed and how they function in communication. It helps us analyze the different components of a sentence, such as the subject, predicate, object, and adverbial phrases.

The Azerbaijani language is a SOV (subject-object-verb) language, which means that the subject typically comes before the object and the verb comes at the end of the sentence. Sentence theory helps us understand these word order patterns and the rules governing sentence formation.

Additionally, sentence theory helps us identify the different types of sentences in Azerbaijani, such as declarative, interrogative, imperative, and exclamatory sentences. It also helps us understand how sentences are transformed in different tenses, moods, and voices.

Overall, sentence theory is crucial for mastering Azerbaijani grammar and effectively communicating in the language. It provides a systematic approach to understanding sentence structure, word order, and sentence types.
