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
hau-
verb.to lie
A verb in the Gnomish Lexicon of the 1910s appearing as G. hau- “lie” based on primitive ᴱ✶haw- (GL/48).
Neo-Sindarin: The root ᴹ√KHAW “rest, lie at ease” appears in Tolkien’s later writings, so I would retain ᴺS. haw- “to lie” as a derivative of this later root, conjugated like S. caw- “taste”: hewin vi chaust “I lie in bed”. I would assume it has the connotation of lying for the purpose of rest and relaxation (“lie at ease”), as opposed to more semantically neutral ᴺS. caeda- “to lie”.
