Meaning & Origin of Io
Origin: Ancient Greek (mythological name, deeper root uncertain).
A common claim: Io is often said to mean 'moon'. Actually: Io doesn't etymologically mean 'moon' — she's a figure from Greek myth, and the Jovian moon was simply named after her; the word's own root is unresolved (some link it to 'violet', but this isn't settled).
