The article is devoted to the study of the linguistic features of the poetic heritage of the Persian-speaking poet Muhammad Iqbal, in particular, the lexical-semantic features and processes of positional use of homonyms in poetry. The article examines the lexical features of homonyms and homonymous words in the Persian poetry of Muhammad Iqbal. One of the topical aspects of studying the linguistic features of the poetic heritage of Iqbal is determining the place of the Persian language in his life, the reasons for its use in the poet's work, since Iqbal is one of the few poets for whom Persian is not the native language and the language he didn’t speak. The material for the study was excerpts from the poet's work and his poem in Persian. It should be noted that Muhammad Iqbal, most of his poetry, reflecting his social, political and philosophical views, wrote in Persian.
