Fai is a compact, cross‑cultural given name with several roots. In Cantonese, it often romanizes the characters 輝/暉, meaning “radiance,” “shine,” or “sunlight,” a popular morpheme in masculine given names. It appears frequently as the second syllable in Hong Kong names (e.g., Ka‑fai, Wing‑fai) and can also stand alone in modern usage. In Thai, Fai (ไฟ) means “fire” or “light,” widely used as a lively, unisex nickname. In English‑speaking contexts, Fai sometimes functions as a streamlined variant of Faye/Fay, linked to Old French fae “fairy” or the later virtue sense “faith.”

Usage has been steady in Cantonese‑speaking communities throughout the 20th century and has broadened globally via diaspora and media. Variants and related forms include Faye, Fay, and Fae in English, while the Mandarin equivalent for the Cantonese 輝/暉 is Hui. Overall, Fai conveys brightness, vitality, and a modern, minimalist style.
