Keely is a gender-neutral name of Irish origin, deriving from the Irish word caoil, meaning “slender.” It’s generally a shortened form of the girl’s name Caoilfhionn (anglicized as Keelin), which combines caoil with fionn, meaning “fair.” Alternatively, it may be a nickname for the boy’s name Caolán, also meaning “slender,” which is sometimes anglicized as Keelan or Kelan. You may opt to use this short and sweet name as a nickname for one of its longer forms, or simply as a name on its own.
