verb. to lick

A noun appearing as N. lhâf “lick” (with Noldorin-style infinitive form lhebi) in The Etymologies of the 1930s from the root ᴹ√LAB of the same meaning (Ety/LAB) where the initial initial *l* was unvoiced to *lh* as was the case in Noldorin of the 1930s.

Conceptual Development: This verb was G. lav- “lick” in the Gnomish Lexicon of the 1910s (GL/53), clearly based on the early root ᴱ√LAVA since the unvoicing of initial l was not a feature of Gnomish in the 1910s.

Neo-Sindarin: Most Neo-Sindarin writers adapt this word as ᴺS. lav- “to lick” since the unvoicing of initial l was also not a feature of Sindarin in the 1950s and 60s.
