Meaning and origin of Rhea
Rhea is often said to mean “uncertain; possibly flowing or earth”; the origin is uncertain, though it is usually linked to Greek roots.
Rhea is the name of the Titaness of Greek mythology who was the wife of Cronus and the mother of Zeus, Hera, Poseidon and their siblings. The meaning is uncertain; it has been linked to a Greek word for flowing and to words for earth, but no explanation is agreed. In Roman legend Rhea Silvia was the mother of the twins Romulus and Remus, the founders of Rome. A moon of Saturn also bears the name. Rhea is short, soft and classical. Ria and Rea are variant spellings, and in India Riya is a separate name with a similar sound.
