G. lavra- v. “to lap (of animals), suck up” (Category: to Lick)
The verb G. lavra- “lap of animals, suck up” appeared in the Gnomish Lexicon of the 1910s (GL/53), clearly based on the early root ᴱ√LAVA “lick” (QL/52).
Neo-Sindarin: Since this early root survived as √LAB in Tolkien’s later writings, I’d retain ᴺS. lavra- “to lap (of animals), suck up” for purposes of Neo-Sindarin.
