Kais is an alternate transcription of the Arabic name قيس (see Qays). The name is used predominantly in Arabic-speaking regions and carries the meaning of "measurement" from its root. It is closely linked to the tragic love story of Qays and Layla, immortalized in classical Arabic and Persian literature. Qays ibn al-Mulawwah, known as Majnun ("the mad one"), was a Bedouin poet who went insane from his unrequited love for Layla. Their tale was popularized in the 12th century by the Persian poet Nizami Ganjavi in his poem Layla and Majnun, which became a seminal work of romantic literature.
The spelling Kais offers a phonetic adaptation that, along with the variant form Qays and the Maghrebi variant Kaïs, reflects different transliteration conventions across the Arab world and beyond. While rooted in classical poetry, the name remains in use today as a distinct first name for boys throughout the Arabic-speaking diaspora.
Although Qays is the gender-neutral counterpart sharing the same etymology, the masculine form prevails. The name carries cultural resonance through its legendary bearer—the heartstruck poet—and continues to evoke themes of passion and longing embedded in the Layla and Majnun narrative.
