λόγχη

Possibly from Proto-Indo-European *pleh₂k- (“to hit”), compare Latin lancea (“lance”) and Old Armenian գեղարդն (gełardn, “spear”), or a Semitic borrowing corresponding to Hebrew רֹמַח‎ (rómaḥ, “spear”), Arabic رُمْح‎ (rumḥ, “spear”) etc. (see the Arabic), but Beekes leaves the etymology unexplained.
