A word appearing as G. orfing (orf-fing) “pear” in the Gnomish Lexicon of the 1910s (GL/63). Its first element is clearly G. orf “apple” and its second element seems to be G. fing “narrow” (GL/35) as suggested by Matt Dinse, so perhaps “*narrow-apple”.

Neo-Sindarin: I’d retain ᴺS. orfing for purposes of Neo-Sindarin, but would assume its second element is S. fing “hair”, so “*hair-apple” given the fuzziness of some pears.
