A noun in the Gnomish Lexicon of the 1910s glossed “a plain” (GL/23), probably derived from the root ᴱ√PALA “flatness” as suggested by Christopher Tolkien (LT1A/Palúrien; QL/071).

A noun appearing as G. nogin “boy, lad, urchin” in the Gnomish Lexicon of the 1910s (GL/61); its derivation is unclear since no nearby words seem to be related, but it could be a variation on G. naug “a dwarf” (GL/59).
Neo-Sindarin: I think this word may be salvageable as Neo-Sindarin ᴺS. nogen, reinterpretted as a derivative of the root √NUK “stunted”, originally an adjective ✱nukina used to refer to short persons or children in a less-than-flattering way. Given its glosses, I would use this word mainly for a mischievous or irritating male child; for a more ordinary word for “boy”, I’d instead use S. ion(n).

The metal G. ladog was mentioned in passing in the Gnomish Lexicon of the 1910s under the entry G. giltha “white metal” (GL/38). It is clearly the cognate of ᴱQ. latúken “tin” as suggested by Christopher Tolkien (LT1A/Tilkal).
Neo-Sindarin: I retained ᴺS. ladog “tin” for purposes of Neo-Sindarin as there are no other alternatives in Tolkien’s later writings.
