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.

carma-cundo
proper name. Helm-guardian
A title of Minalcar as the regent of Gondor (PM/260). This name is a compound of carma “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”.
carda
deed
carda noun "deed" (PE17:51). Cf. car #3. The word may contain the ending -da (q.v.) denoting the result of the corresponding verbal action.
carda
noun. deed
carda
noun. deed
Quenya noun for a “deed”, a combination of the verb car- “to do” and the verbal suffix -da used for the product of an action (PE17/51; PE22/152), thus literally “✱a thing done”.
Conceptual Development: Perhaps the earliest precursor of this word is ᴱQ. karma “shape, fashion; act, deed” in the Qenya Lexicon from the 1910s of similar derivation (QL/45). In The Etymologies from the 1930s, the word appeared as ᴹQ. kar (kard-), but this gloss was rejected and replaced by ᴹQ. kar “building” (Ety/KAR). The form karma “deed” also appeared in some later writings, but was rejected (PE22/138).
