There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

reg

root. edge, border, margin

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).
