The present article examines the content and linguistic features of the realization of the concept of “happiness” in the English language. Drawing on semantic, pragmatic, and cognitive approaches, the study explores how happiness is encoded through lexical units, phraseological expressions, and contextual usage. Special attention is given to the interaction between language and culture, as well as to the role of discourse in shaping the interpretation of emotional concepts. The findings demonstrate that happiness is a multifaceted concept that reflects not only individual emotional states but also cultural values, social norms, and communicative intentions.
