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

fwegra-

verb. to sweep

A word appearing as G. fwegra- “sweep” in the Gnomish Lexicon of the 1910s, a verb form of G. fweg “broom” (GL/36).

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