The phenomenon of repetition actually exists in language.The general concept of repetition can be defined as the repetition of separate elements of the language (glossems) -sounds, morphological parts of the word, words and syntactic constructions.Accordingly, it is possible to say that there is a whole system of repetitions in the language: sound repetition, morphological repetition, lexical repetition, syntactic repetition.Thus, the place of lexical repetition in the general repetition system is determined.More or less research work has been carried out on syntactic and morphological, as well as phonetic repetitions in Azerbaijani linguistics.But lexical repetitions have not yet attracted attention.However, in our language, such repetitions are very widespread and have rich features.All types of repetition that will be discussed here are related to grammatical events and the sentence structure of the Azerbaijani language.We would like to pay particular attention to the words "sentence structure" (also "sentence structure").Because sometimes "lexical repetition" means that two expressions (sentences, phrases) have the same structure or the phenomenon of syntactic parallelism.However, lexical parallelism is more of a stylistic phenomenon than a grammatical one.One of the verbalization ways of background knowledge is the use of constructions with lexical repetitions.In theory, background knowledge can be described on the basis of three tandems:-Extralinguistic and metadyl knowledge -Descriptive and prescriptive -General and local knowledge The first one of these tandems deals with either extralinguistic factors in reality or linguistic conventions, the latter concerns with either statistic norms based on inductive generalizations or normative imaginations.The third one deals with the scope of information or its importance for the speaker of a given language.Interpretations of the texts can be realized not only with linguistic knowledge, but also extralinguistic and contextual knowledge.
