The field principle of the system organization of linguistic facts is considered one of the most important achievements of modern linguistics. “Functional-semantic field” suggests grouping the language means interacting on a semantic-functional basis and their system-structural organization. The concept was developed by the well-known linguists J. Trier, B. Pottier, A. Bondarko, E. Coseriu and S. Berejan. The advantage of functional- semantic approach gives the opportunity to study language in its concrete realization, in action, as well as to analyze the means of rendering extralinguistic phenomena. The corpus of money-related language (in its literary, terminological and verbal embodiment) differs in richness from nation to nation, being determined by its historical development, social beliefs, and dominant ideology. The English language is very rich in money-related lexical units, which are recognized and widely used in the media, fiction, and didactic literature in both Great Britain and the United States of America. The widest variety of nominal and attitudinal expressions traditionally comes from the USA. The article is devoted to the peculiarities of functioning of the functional-semantic field in the English language. The author defines the concept “functional-semantic field”, reveals lexemes denoting “money” (conceptual field), makes the semantic analysis of the constituents of the field (semes) and presents their idiomatic micro-fields.
