"Variant of Cleo"
The name Kleo is commonly a unisex name from the "Greek" origin.
Kleo is a spelling of Cleo, the English form of Greek Kleio, the name of one of the Muses in Greek myth. The Greek noun kleos means fame or glory, and the K spelling reflects the kappa that begins the Greek form. The name entered United States birth records recently, and the Kleo spelling is a later alternative to the long-established Cleo.
Cleo means "The proclaimer.".
The pronunciation of Kleo is KLEE-oh.
