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.
nib
noun. snowflake
teb
noun. point, nib, neb, nose
A word in the Gnomish Lexicon of the 1910s glossed “point, nib, neb, nose” (GL/69). Its derivation is unclear.
tenc
noun. pen, nib
eg
noun. point
gwint
noun. face
A noun for “face” in the Gnomish Lexicon of the 1910s, related to the verb G. gwinta- “to see” (GL/46); see that entry for possible etymologies.
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
A word appearing as G. nib “snowflake” in the Gnomish Lexicon of the 1910s (GL/60), clearly based on the early root ᴱ√NIQI “white” (QL/66), since medial and final *q* became *p* and then *b*.
Neo-Sindarin: I think this word can be salvaged as Neo-Sindarin ᴺS. nibis “snowflake”, cognate of Q. niquis.
