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.

noun. gore

An archaic noun for “gore” in the Gnomish Lexicon of the 1910s derived from primitive ᴱ✶meχse via the vocalization of the spirant χ before s: eχ > ei > ai (GL/56). It is clearly related to the early root ᴱ√MEHE “ooze‽” from the contemporaneous Qenya Lexicon that was likewise the basis for “gore” words (QL/60).
