Although some ideas have been put forward in Azerbaijani linguistics about elliptical sentences, their structural models, and their types according to the elliptical member, the role of such sentences as a means of expression of human feelings and thoughts in a certain psychological situation and their emotional functions have not been discussed. Elliptical sentences are sentences in which one or more main parts of a sentence, as well as structural elements (connectors, particles) are omitted, but can be easily reconstructed by analogy, adaptation to the context, situation or content of the sentence. At the same time, having an emotional-expressive tone, they gain different connotations as a result of interaction with the components of the text and emotional units. The article discusses the fact that elliptical sentences express emotional and evaluative meaning at the syntactic level, create dynamism in speech, natural conversation intonation, and perform the function of transmitting various emotions. In particular, the models of elliptical sentences formed by the reduction of certain parts of speech, which are the means of expression of the primary and secondary members, and sometimes the members of complex sentences, their use in dialogic speech, their position as a means of expression of emotions are considered.
