There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

Gnomish

mara-

verb. to dwell

mara

noun. sand

(m)bara-

verb. to dwell

gwadh-

verb. to dwell

A verb appearing as G. gwadh- “dwell” in the Gnomish Lexicon of the 1910s with a (deleted) primitive form gu̯ađ (GL/46), likely an allusion to the early root ᴱ√ẆAÐA from the contemporaneous Qenya Lexicon (QL/102). In that document, Tolkien gave the Gnomish form as {gwath- >>} gwar-, however, which might align with the deleted primitive form ᴱ✶gu̯ara- “dwell” from the Gnomish Lexicon (GL/38).

A noun with variants marol and mara in the Gnomish Lexicon of the 1910s glossed “sand”, probably a derivative of the root ᴱ√MARA (GL/56); see the entry on the root for further discussion. In later writings, Tolkien used N. lith for “sand”.
