Leily is a variant of Leila, from Persian and Arabic usage meaning night or dark beauty.
Leily is a variant spelling of Leila or Layla, one of the most celebrated names in Arabic literary and musical tradition. The name derives from the Arabic *laylā*, meaning "night" or, more poetically, "intoxication" — a reference to the dizzying, dark beauty of a woman who overwhelms the senses as night overwhelms the day. Its earliest and most famous appearance is in the tragic romance of *Layla and Majnun*, a love story composed in verse by the Persian poet Nizami Ganjavi in the 12th century.
The tale — in which the poet Qays becomes so consumed by love for Layla that he is called *Majnun* ("driven mad") — became one of the defining love narratives of the Islamic literary world, often compared to Romeo and Juliet for its themes of passion and impossibility. The name traveled westward through Ottoman culture and eventually into European consciousness, gaining particular resonance in the English-speaking world after Eric Clapton's urgent 1970 rock ballad "Layla" — a song written, famously, out of his unrequited love for Pattie Boyd. That song introduced millions to a name that had previously lived mostly within Middle Eastern and South Asian communities.
Since then, Layla and Leila have climbed steadily in Western name charts, while variant spellings like Leily, Leilah, and Leyla have proliferated. Leily, with its soft double vowel ending, carries a slightly more delicate visual impression than Layla — closer to the Persian poetic tradition than to Western pop culture. It is a name steeped in longing, beauty, and literature, carrying centuries of romantic association without feeling heavy or dated.
