Qafia is a term used in Urdu and Persian poetry that refers to the rhyming pattern in a verse. It specifically denotes the consonant sound that appears at the end of the second line of a couplet, creating a musical quality in the poem. This technique enhances the lyrical flow and emotional impact of the poetry. In addition to its role in poetry, qafia is often paired with radif, which is a repeated phrase or word that follows the qafia. Together, they form a crucial part of the structure in traditional forms of poetry, such as ghazal, allowing poets to express complex emotions and themes in a rhythmic manner.
