In 30 seconds: Koi is a Japanese boy's name meaning 'carp', and as a homophone, 'love' or 'affection'. That double sense gives a very short name real depth.
Koi comes from Japanese, where it names the carp, the colorful fish kept in ornamental ponds. As a homophone it also means love or affection, so the single syllable holds two meanings at once. Sources record no spelling variations, leaving the name clean and minimal.
The sound is soft and immediate, a single open syllable that is easy to say in any language. The carp and the love meanings together give Koi a gentle, layered quality despite its brevity.
Did you know? The meaning usually attached to Koi is 'romantic or passionate love, affection, to yearn for', and that core idea is what gives the name most of its long-term appeal.
