A root in The Etymologies of the 1930s glossed “bind” but without derivatives (EtyAC/RAP). The element S. raph (“?rope”) in S. Udalraph “Stirrupless” (“?without (U-) foot-rope”) might be related (UT/313).

tor
root. brother
Tolkien gave this root in The Etymologies of the 1930s as ᴹ√TOR “brother” with derivatives like ᴹQ. toron and N. tôr of the same meaning (Ety/TOR). Hints of the roots continued use appear in the 1959 term Q. melotorni “love-brothers” for close male friends (NM/20). In notes from the late 1960s, Tolkien gave Q. háno and S. hanar as the words for “brother”, both from the root √KHAN. Nevertheless, I think it is worth retaining ᴹ√TOR to represent more abstract notions of “brotherhood” for the purposes of Neo-Eldarin, for “metaphorical” brothers as opposed to Q. háno/S. hanar for brothers by blood.

A rejected root for “friendship” in The Etymologies of the 1930s (EtyAC/ÑEL), apparently replaced by ᴹ√N(D)IL.
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.
