Means "night" in Arabic. This was the name of the object of romantic poems written by the 7th-century poet known as Qays. The story of Qays and Layla became a popular romance in medieval Arabia and Persia. The name became used in the English-speaking world after the 1970 release of the song 'Layla' by Derek and the Dominos, the title of which was inspired by the medieval story.
