Tolkien gave this root in The Etymologies of the 1930s as ᴹ√THEL and extended form ᴹ√THELES with the gloss “sister” and derivatives like ᴹQ. seler and N. thêl of the same meaning, both derived from the extended root as made clear by the Noldorin plural thelei < ON. thelehi (Ety/THEL). Hints of the roots continued use appear in the 1959 term Q. meletheldi “love-sisters” for close female friends (NM/20). In notes from the late 1960s, Tolkien gave Q. nésa and S. nethel as the words for “sister”, both from the root √NETH. Nevertheless, I think it is worth retaining ᴹ√THEL(ES) to represent more abstract notions of “sisterhood” for the purposes of Neo-Eldarin, for “metaphorical sister”s as opposed to Q. nésa/S. nethel for sisters by blood.

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.
An onomatopoeic root from The Etymologies of the 1930s serving as the basis for Elvish words for “small gull, petrel” (EtyAC/KWǢ). Similar words also appeared in The Feanorian Alphabet from the late 1930s, derived from ᴹ✶kwǣnē (PE22/32). This root is unusual in that it is the only published root using ǣ (an a-fortified e) as its root vowel.
