Somatic proverbs represent an important segment of phraseological units in many languages, as they are formed on the basis of body-part terms and human physical experience. Such proverbs reflect not only linguistic structures but also cultural values, national mentality, and cognitive models shared by speech communities. This article provides an extended analysis of somatic proverbs with particular emphasis on their synonymy. Special attention is paid to the comparative study of English and Uzbek somatic proverbs. The paper examines theoretical approaches proposed by well-known linguists, illustrates the ideas with numerous examples, and reveals similarities and differences in the use of somatic components across the two languages.
