Gnomish
gulta-
verb. to pour out (tr.)
ultha-
verb. to pour out (tr.)
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!
A verb appearing in the Gnomish Lexicon as G. ultha- “pour out, tr.” (GL/74), hence clearly based on the early root ᴱ√ULU (QL/97). A deleted verb G. gulta- “pour out, tr.” earlier in the document indicates Tolkien considered having the true form of the root be ✱ᴱ√GULU (GL/43).
Neo-Sindarin: If adapted for Sindarin phonology, this verb would become oltha-, but there is already another verb N. oltha- “to dream” (Ety/ÓLOS). As such, I would simply coined a neologism ᴺS. ol- “to pour” derived directly from the root √UL.
