A word appearing as G. cwildred “bat (animal)” in the Gnomish Lexicon of the 1910s, an (agental?) elaboration of G. cwîl “quiet” (GL/28). According to the editors, the first d was circled, perhaps indicating it was optional or lost (cwilred).

Neo-Sindarin: For purposes of Neo-Sindarin, I would revise this word to ᴺS. pillor as an agental form of the Neo-Root ᴺ√KWILID.
