Gandalf’s sword (LotR/280), first named in The Hobbit and translated in that book as “Foe-hammer” (PE17/84; RS/444). Its initial element glam is the plural of glamog “orc” (WJ/391), and its second element is a derivative of the root ᴹ√DRING “beat, strike” (Ety/DRING), apparently a noun *dring “hammer” attested only as an element in this name.

Conceptual Development: The name N. Glamdring appears in The Etymologies from the 1930s, which is the source of the second part of the derivation given above (Ety/DRING).
