A Ghazal is a form of poetry that originated in Arabic literature and later became popular in Persian, Urdu, and other languages. It typically consists of a series of couplets, each expressing a self-contained thought or emotion. The themes often revolve around love, loss, and longing, and the structure usually includes a refrain and a rhyme scheme. Each couplet in a Ghazal can stand alone, allowing for a diverse range of ideas within a single poem. The form has been embraced by many poets, including Mirza Ghalib and Faiz Ahmed Faiz, who have contributed significantly to its rich tradition.
