Origin

Frenetic came into English in the 1300s as frenetik, from Old French frenetike, from Latin phreneticus, which came from Greek phrenetikos, meaning delirious. The Greek word comes from phrenitis, meaning delirium, which comes from phren, meaning mind. Frenetic is a doublet of frantic, which means the two words come from the same source.
