√KHIN root. “child”
A root appearing in Notes on Names from 1957 with the gloss “child” (PE17/157), and again in the Quendi and Eldar essay of 1959-60 with the same gloss (WJ/403). It was the basis for the words Q. hína and S. hên “child”, which were probably inspired by the Adûnaic patronymic suffix -hin that Tolkien introduced in the 1940s as part of Êruhin “Child of God” (SD/358), originally an Adûnaic word but later on used in Sindarin (Let/345; MR/330). This root might be a later iteration of the early root ᴱ√HILI from the Qenya Lexicon of the 1910s whose derivatives had to do with children (QL/40). As evidence of this, the Adûnaic word was first given as Eruhil (SD/341).
