Meaning and origin of Kaleo
Kaleo is a Hawaiian name that means “the voice, the sound”.
Kaleo is a Hawaiian name meaning "the voice" or "the sound," combining the definite article ka with leo, voice. It is used for boys in Hawaii and has spread to the mainland US. The Icelandic rock band Kaleo, which took the Hawaiian word for its name, brought it wider recognition. It is pronounced kah-LAY-oh. The name has a warm, musical sound, and it sits well with other Hawaiian names such as Kai and Makoa. Leo is a ready-made nickname, which also connects it to a very familiar classic.
