A word appearing as G. arn “son” in the Gnomish Lexicon of the 1910s (GL/20), also appearing with the same form and meaning in Gnomish Lexicon Slips modifying that document, but with a new plural form eirn (PE13/110). The word reappeared in Early Noldorin Word-lists of the 1920s but there its gloss was changed from “son” to “child” (PE13/137). In the Early Noldorin Dictionary of the 1920s its only gloss was “child” (PE13/160). There is no sign of this word thereafter.

braith
?. [unglossed]
A verb appearing in the Gnomish Lexicon of the 1910s as G. braitha- “wrap, swathe” based on G. brach “a shawl, plaid, wrap” (GL/23). The form ᴱN. braith also appeared in Early Noldorin word lists of the 1920s (PE13/139), but it was unglossed and whether it was related is unclear.
Neo-Sindarin: Since I retain ᴺS. brach “shawl, wrap”, I’d also keep this Gnomish verb as a derivative of the Neo-Root ᴺ√BARAK “wrap”, but updated to ᴺS. braetha- “to wrap, swathe” since ai became ae in Sindarin of the 1950s and 60s.
