A noun in The Etymologies of the 1930s glossed “mound, heap” derived from the root ᴹ√KUB (Ety/KUB). The forms ᴱN. cum(b) “mound” and G. cûm “mound (especially grave), burial mound” appeared in Early Noldorin Word-lists of the 1920s (PE13/141) and Gnomish Lexicon of the 1910s (GL/27), but these earlier forms were probably derived from ᴱ√KUMU “heap up” (QL/49). This word appeared in the name N. Cûm-na-Dengin “Mound of Slain” in Silmarillion drafts from the 1930s (SM/312, LR/147) as well as its precursors in earlier versions of the tales, but later this name became S. Haudh-en-Ndengin.
Neo-Sindarin: For purposes of Neo-Sindarin, I’d avoid this word and use S. haudh. In later writings the root √KUB was given the new meaning “hide, secrete” (PE22/155).
