Andrea is a given name which is common worldwide for both males and females, cognate to Andreas, Andrej and Andrew. Origin of the name. The name derives from the Greek word ἀνήρ (anēr), genitive ἀνδρός (andrós), that refers to man as opposed to woman (whereas man in the sense of human being is ἄνθρωπος, ánthropos). The original male Greek name, Andréas, represents the hypocoristic, with endearment functions, of male Greek names composed with the andr- prefix, like Androgeos (man of the earth), Androcles (man of glory), Andronikos (man of victory).
