the aesthetics of code switching

Abstract  Some of the figures of speech in Persian language are those that show the rhetorical value of the bilingualism. Tarjema (translation), Molama (bilingual poem), Dhuloghatayn (readable by two languge), Eghtebas (borrowing), Darj (insertion), are these figures of speech. Unfortunately, in rhetorical sources and books, the aesthetic values of these figures have not been explained. However, the aesthetic aspects of these figures can be shown through several theories that discuss code switching considering the fact that some of the theories are commonly used in literature and literary criticism . Therefore, in this essay, it is shown that from these figures, Eghtebas (borrowing) has a higher literary value and importance than others. Moreover, the literary significance of this figure is revealed through several theories.
