ᴹ√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 √KHAN¹. 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.
