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

lalt

noun. dance

A noun appearing as G. lalt “a dance” in the Gnomish Lexicon of the 1910s (GL/52), clearly based on the early root ᴱ√LḶTḶ “dance” (QL/55), probably with [[g|long syllabic [ḹ] becoming [al]]].

Neo-Sindarin: For purposes of Neo-Sindarin, I would adapt this word as ᴺS. lilt for better compatibility with the later root ᴹ√LILT “dance”, as suggested by Fiona Jallings.
