A root in The Etymologies of the 1930s glossed “edge, border, margin” with derivatives like ᴹQ. réna of similar meaning and N. rhain “border” (Ety/REG). ᴹ√REG replaced a rejected variant ᴹ√RAG (EtyAC/REG). The root is evident in only one name: N. {Duil Rain >>} Emyn Rhain “Border Hills” in Lord of the Rings drafts from the 1940s (TI/268, 313), called S. Emyn Muil “Drear Hills” in the published version of The Lord of the Rings (LotR/373; RC/334).
