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

tump

noun. shed

A noun appearing as G. tump “shed” in the Gnomish Lexicon of the 1910s (GL/71), clearly a cognate to ᴱQ. tumpo “shed, barn” which was derived from either ᴱ√TṂPṂ or ᴱ√TUPU (QL/93, 95).

Neo-Sindarin: Since √TUP “cover” survived in Tolkien’s later writings, I think this word can be salvaged as ᴺS. tump “shed”, though it does conflict with [N.] tump “hump”.

bada-

verb. to build

tub-

verb. to cover
