This article presents new perspectives on the definition of phrases and compound words in Uzbek and English linguistics, analyzes the essence of semantic commonality from both philosophical and linguistic perspectives, and it is mentioned that the syntactic relationships of the components of these language units are present. An attempt has been made to compare Uzbek compound words with alternative English variants and to analyze the ratio of these interlingual semantic commonalities. Taking into account the diversity of semantic variations in them, the diversity of characteristics inherent in the nature of the languages of form and content relations, these linguistic units were divided into groups. In all languages of the world, word combinations have gradually changed into compound words due to certain semantic changes in their meaning. The meaning, understood as a word combination, began to be called and indicated by a third thing and phenomenon. Two (and more) words in the composition named a new object while preserving their meanings (which changed completely in cases of meaning transfer). As long as languages live, this phenomenal event of language continues. It further enriches the vocabulary of the language, and the combination of words becomes compound words and stabilizes. Hence, these linguistic phenomena have become a customary practice in the evolution and advancement of languages, and serve as an inherent means of enhancing the potency of language expression.
