The article is devoted to the analysis of the culturally specific semantic field «mountain» in the English vocabulary. According to the list of P600 mountains, there are 120 mountains in Great Britain, 82 of which are located in Scotland. According to another classification, the Mаrylins, including in addition the mountains and hills, that number rises to 1,552. Being of significance in the landscape of Great Britain with an extensive mountain system and a system of highlands, it is logical to assume that this phenomenon has received a rich embodiment in the English language vocabulary. Another object of interest is the theory of the semantic field, the study of which, despite its long history, attracts the attention of scientists. Currently, linguistics pays great attention to the study of the system organization of the vocabulary of a language, which does not imply a separate analysis of its lexical units, but their analysis in all possible connections and relationships. The relevance of this work lies in the description of the unexplored linguistic phenomena, the semantic field «mountain» at an early unexamined level, the choice of which is dictated by modern realities – the growing interest in nature; secondly, this study is performed in the important for modern linguistic scientific direction – the study of the systematic vocabulary. The analysis is carried out with the help of the method of the componential analysis and of a directed selection of material from lexicographic sources. Summing up one can conclude that semantic field confirms culturally specific nature of the semantics of «mountain».
