A root in The Etymologies of the 1930s glossed “male” and used in this sense for both people and animals (Ety/ƷAN). Its principle derivatives are ᴹQ. hanu/N. anw “male (person or animal)”, so it might more properly be ✱ᴹ√ƷAN+U.

A root in The Etymologies of the 1930s glossed “bind” with derivatives like ᴹQ. vére/N. gwaedh “bond, troth, compact, oath” and ᴹQ. vesta-/N. gwesta- “swear”, though Tolkien deleted Quenya derivatives of this root beginning with ves- saying they fell out of use due to conflict with ᴹ√BES “wed” (Ety/WED). This root might be a later iteration of the hypothetical early root ✱ᴱ√FEDE indicated by words in the Gnomish Lexicon of the 1910s like G. fedhin “bound by agreement; ally, friend” and G. fedhra- “unite in a band” (GL/34), but the 1910s and 1930s forms are rather dissimilar so it is hard to say.
A root in The Etymologies of the 1930s glossed “doom, final end, fate, fortune” = “final bless”, an extended form of ᴹ√MAN “holy spirit”, with derivatives ᴹQ. manar or mande and N. manað, apparently with the same meaning as the root (Ety/MANAD). In Quenya it was partially blended with ᴹ√(M)BAD in names like ᴹQ. Mandos.
