Origins

Uncertain. It has been proposed that the term derives from ad- + Proto-Indo-European *mod-ti-, itself from the root *med- (“to measure”). However, De Vaan suggests that the existence of an o-grade preform *mod-ti- is “questionable.” Another theory suggests that the term derives from ἄμυξις (ámuxis, “tearing, mauling”), from ἀμύσσω (amússō, “to scratch, lacerate”). However, this latter proposal is rejected by the philologist Manu Leumann.
