In poetry, the ghazal (Arabic/Persian/Uru: غزل; Hindi: ग़ज़ल, Turkish gazel) is a poetic form consisting of rhyming couplets and a refrain. Each line must share the same meter. The Arabic word "ghazal" is pronounced roughly like the English word "guzzle", but with the first, g-like consonant further back in the throat. A ghazal may be understood as a poetic expression of both the pain of loss or separation and the beauty of love in spite of that pain. The form is ancient, originating in 6th century pre-Islamic Arabic verse. It is derived from the Arabian panegyric qasida. The structural requirements of the ghazal are similar in stringency to those of the Petrarcan sonnet. In its style and content it is a genre which has proved capable of an extraordinary variety of expression around its central themes of love and separation. It is one of the principal poetic forms the Indo-Perso-Arabic civilization offered to the eastern Islamic world.
