A noun appearing as N. camland “palm of hand” in The Etymologies of the 1930s as a combination of N. cam “hand” and N. lhann “wide” (Ety/LAD). It is not clear why this word ends in nd rather than reducing to n(n) as is usual.
Conceptual Development: There were some similar words for “palm of the hand” in the Gnomish Lexicon of the 1910s: G. mablad or mablod plus G. mavlant, all with an initial element G. mab “hand[s]” and a second element like G. lad “a level, a flat” or G. blant “flat” (GL/23, 52, 55).
Neo-Sindarin: This word is often adapted as ᴺS. camlann for Neo-Sindarin, as suggested in HSD (HSD), in keeping with the trend of final nd becoming n(n) in polysyllable in both Noldorin and Sindarin.
Earliest Elvish name for the Wetwang appearing in Lord of the Rings drafts from the 1940s (TI/268), a combination of palath “surface” and otherwise unattested nenui “wet”, as suggested by Roman Rausch (EE/2.38).
