A rejected noun meaning “valor” developed from the root ᴹ√BER (Ety/BER), perhaps from a primitive form *✶berette. The word was probably rejected when Elbereth change from an Ilkorin to a Noldorin name.
A Doriathrin noun for “beech (tree)”, properly referring to Hirilorn with a true meaning of “three trunks” (Ety/NEL). Tolkien indicated it was a combination of neld “three” and orn “tree”, though it is unclear why the final -n vanished. He marked this derivation with a “?” perhaps because of this uncertainty.
