Q. Carma-cundo pn. “Helm-guardian”
A title of
Minalcar as the regent of Gondor (PM/260). This name is a compound of
carma¹ “helm” and
cundo “guardian”. Elsewhere
cundo means “prince” or “lord” (Ety/KUN, PE17/117). This might still apply here, since Minalcar was heir to the throne. Furthermore,
the crown of Gondor was originally a helmet (LotR/1043 note #1), so perhaps:
Carma-cundo = “Crown Prince”.
