thar

root. vigour

der

root. hard, difficult

A root in linguistic notes from 1959 used for the sense “hard, difficult” in Sindarin because other roots like √GUR > S. gor- gained a very negative sense due to collision with the roots √ÑGOR “horror” and √ÑGUR “death” (PE17/154). Tolkien first gave this root as √DIR before switching it to √DER. There is no indication of its use in Quenya, so it is probably a Sindarin-only innovation.

(ñ)guruk

noun. horror

il

root. all

A root meaning “all” in Tolkien’s writings from the 1930s through 1960s (VT48/25) with derivatives in both Quenya and Sindarin, the most notable being Q. Ilúvatar “All-father” (MR/39). Its earliest precursor is the root ᴱ√ILU “ether, the slender airs among the stars” from the Qenya Lexicon of the 1910s, whose derivatives include various sky-words as well as ᴱQ. Ilúvatar, since in this early period the name meant “Heavenly Father” (QL/42). The meaning of the root shifted to ᴹ√IL “all” in The Etymologies of the 1930s (Ety/IL), and it retained this sense thereafter.
