Slender or narrow
Kilea is likely a modern phonetic variation of the Irish name Kyla or the Hawaiian name Kilea. In its Irish roots, it is a feminine form of Kyle, referring to a narrow strait or channel. In a Hawaiian context, it can be interpreted as 'to go' or 'to move', though it is most commonly used in the US as a creative spelling variant.
