Hallacar masc. name, apparently "tall helmet": halla + car (cf. Eldacar for the latter element) (UT:210)
masculine name. *Tall Helm
Word Gloss halla “tall” carma “helm”
carma (2) noun "helm" (helmet) in Carma-cundo ("k") "Helm-guardian" (PM:260). Notice that in PE17:114, Tolkien indicated that he rather wanted carma to mean "tool" or "weapon", leaving the status of carma "helmet" uncertain. Possibly shortened to -car in the names Eldacar (Elfhelm?), Hallacar (Tall-helm?) Cf. also cassa in Etym.
Word Gloss cas “head, head, [ᴱQ.] top, summit”
