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

lith-

verb. to go, depart, be over, finish, end, die

A verb in the Gnomish Lexicon of the 1910s glossed “go, depart, be over, finish, end, die” (GL/54). The early root ᴱ√lith- also seems to have been related to time (see G. laith “time, the course of time”), so the meaning of this verb may have originally been exclusively temporal, only later spatial.

mara

noun. sand

marol

noun. sand

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”.

thith

noun. dust

A noun in the Gnomish Lexicon of the 1910s glossed “dust”, appearing below other forms like G. thisin “parched, withered” (GL/73). The latter is clearly a cognate of ᴱQ. sisin from the contemporaneous Qenya Lexicon, and hence is derived from the root ᴱ√SISI as it appeared in that document (QL/84), though its Gnomish derivatives make it clear the actual root was ✱ᴱ√ÞISI.
