More about hero
The English singular noun hero is formed from the plural heroes, which comes from Latin hērōes, the plural of hērōs “(mythical) hero.” Hērōs comes from Greek hḗrōs (plural hḗrōes) “hero,” a very ancient word that meant many things to the Greeks. A compound noun trisērohei, literally “Thrice Hero,” possibly the name of a deity “Clan Ancestor (?),” appears on a Linear B tablet from Pylos, dating to the 13th century b.c. In the Iliad, hḗrōs means “warrior,” and often little more than “man,” and not a semidivine being. In later Greek, hḗrōs was a semidivine being with his own cult, usually local, the only exception being Hercules (Heracles). (Greek Hērākléēs, also spelled Hērāklês, means “Glory of Hera.” Hḗrā is the Greek feminine form of hḗrōs; she is a daughter of Cronus and sister and wife of Zeus. Her name occurs next to the name of Zeus on the same Mycenaean Greek text, which makes likely the assumption that Hera was already honored as the consort of Zeus.) Unfortunately, hḗrōs and its derivative noun Hḗrā, like 60 percent of Greek vocabulary, have no satisfactory etymology. The various etymologies proposed suffer from various degrees of improbability. Hero entered English in the 16th century.
