An element appearing in the names Gimilzagar (UT/227) and Belzagar (UT/222). The Quenya name of Gimilzagar is Calmacil, the final element of which means “sword”, so perhaps this word means the same thing. Most authors have suggested this interpretation (AAD/24, AL/Adûnaic, EotAL/ZAG’R, NBA/20) as well as its possible relationship to azgarâ- “wage war”.
