Takhallus is a term used in Urdu poetry to refer to a pseudonym or pen name adopted by poets. It allows them to create a distinct identity in their literary work, often reflecting their personality or themes they explore. This practice is common in South Asian literature, where poets use their takhallus to sign their poems, making their work recognizable. The use of takhallus can also serve as a way for poets to express their emotions or philosophical beliefs. Famous poets like Mirza Ghalib and Allama Iqbal have employed takhallus in their writings, contributing to their unique styles and legacies in Urdu literature.
