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

piog

noun. berry

A word in the Gnomish Lexicon of the 1910s glossed “berry”, the cognate of ᴱQ. piukka “blackberry” (GL/64; QL/74). The io is probably the result of the Gnomish sound change whereby iu became io (PE15/13).

Neo-Sindarin: In Sindarin, iu became ŷ, so this word might be adapted as ᴺS. pŷg, but I prefer to use ᴺS. dod for “berry”.

dod

noun. berry

The word G. dod “berry” appeared in the Gnomish Lexicon of the 1910s above G. dod- “fall down, drop” (GL/30), so perhaps originally meaning “✱a thing dropped”.

Neo-Sindarin: I would retain ᴺS. dod “berry” for purposes of Neo-Sindarin as a derivative of the Neo-Root ᴺ√DOT “drop”.
