n. countablen. a person who is incredibly strong or brave. It comes from the name of a famous hero in ancient Greek stories who finished twelve impossible tasks.

From Latin Herculēs, from Etruscan 𐌇𐌄𐌓𐌂𐌋𐌄 (hercle), from Ancient Greek Ἡρακλῆς (Hēraklês), apparently cognate of Ἥρα (Hḗra, “Hera”) and, according to Haudry, from Proto-Indo-European *yóh₁r̥ (“year, season”) + κλέος (kléos, “glory”).
When used as a common noun to describe a strong person, it is typically not capitalized, though the mythological figure always is.
