Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!

Gnomish

ocha

noun. fleece

A word for “fleece” in the Gnomish Lexicon of the 1910s derived from primitive ᴱ✶ou̯χē (GL/62) and hence based on the early root ᴱ√OWO having to do with wool (QL/71).

octha

noun. knee

The word G. octha “knee” appeared in the Gnomish Lexicon of the 1910s (GL/62), clearly a cognate of ᴱQ. okka “knee” (QL/70).

Neo-Sindarin: In the VQP (VQP), Sami Paldanius proposed adapting this word as the neologism ᴺS. ogod “knee”, by analogy with the revision of G. leptha “finger” to [N.] lhebed.
