Ailin is a masculine name with multiple cultural origins. In Irish tradition, it's derived from Ailín, a diminutive of Ailill, meaning 'elf' or 'noble.' In Chinese, Ailin (爱林) can mean 'love of forest.' The name also appears in Spanish-speaking countries, possibly derived from Eileen or as a variant of Alan. With its soft sounds and short length, Ailin has a gentle, contemporary feel despite its ancient roots. While traditionally more common for boys in its original cultures, the name has sometimes been used for girls in international contexts. Ailin remains relatively uncommon but offers a cross-cultural appeal with its melodic sound and meaningful heritage.
