THEORETICAL FOUNDATIONS OF PHRASEOLOGICAL UNITS IN HETERO-SYSTEM LANGUAGES
This article discusses the theoretical foundations of phraseological units in different systemic languages. The material of the study is the linguistic data of English and Azerbaijani languages. Phrases in the language are divided into two main parts: stable and free phrases. Despite the division into two parts, stable and free phrases are not mutually exclusive units and do not contradict each other. The research methods are descriptive, descriptive-comparative and typological-comparative methods of linguistics.
