ᴱ√GWELE root. “*boil, bubble”
A root in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. wele-/G. gwel- “to boil, bubble” and ᴱQ. welbe/G. gwelc “bubble” (QL/103; GL/44). There are no signs of this root in Tolkien’s later writing, but I think it is worth retaining this root for the purposes of Neo-Eldarin, since there are no other good candidates for “boil” words elsewhere in the published corpus. I’d update the form to ᴺ√WEL, however, otherwise the (Neo) Sindarin forms would begin with b-.
