Gnomish

fwegli

noun. brush

A noun appearing as G. fwegli “brush” in the Gnomish Lexicon of the 1910s, an elaboration of G. fweg “broom” (GL/36).

Neo-Sindarin: The fw- in G. fwegli is likely the result of ancient sw-, so I would adapt this word as ᴺS. hwegol “brush” for purposes of Neo-Sindarin since sw- became hw- in Sindarin of the 1950s and 60s.
