Etymology

A compound: from Ancient Greek δι- (di-, “two-, double”) + φυή (phuḗ, “growth, nature”) + -ής (-ḗs), with the adjective ending -ής: “of double nature”.[1][2] The first element is the combining form of δίς (dís, “twice”), and φυή (phuḗ) is the noun of φύω (phúō, “to grow, to bring forth”).[2][1] The same pattern gives εὐφυής (euphuḗs, “well-grown, gifted”).[2]

Earliest recorded meaning

It is first recorded in the 5th century BC for beings of a double, half-human form: Herodotus applies it to the snake-woman, half maiden and half viper, whom the Scythians made the mother of their race, and Sophocles' Heracles to the Centaurs.[3][4]

Semantic evolution

The word stayed tied to mixed beings: Plato's Cratylus uses it of Pan, half man and half goat, and later writers of Cecrops, the first king of Athens, represented as man above and serpent below.[3][4] Ancient scholars reinterpreted Cecrops' double nature as double sex, or as double race, Egyptian and Greek, and Tzetzes even as two languages.[4][3] In Orphic poetry it describes Eros and other androgynous deities.[4][3]

Aristotle gave it a neutral anatomical sense, “twofold, paired”, for organs that come in pairs such as the eyebrows and breasts, and Galen called the biceps the “double” muscle.[3][4] Christian writers of the 4th and 5th centuries used it in the debates about the natures of Christ.[4]

Modern Greek has it as a learned word, Modern Greek διφυής (difyís), “of a double nature” (the centaur is a “double-natured being”) and, in medicine, “made of two like parts”.[5][6]
