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.
Doriathrin
ber
noun. valiant man, warrior
bereth
noun. valor
galbreth
noun. beech
neldor
noun. beech
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.
Conceptual Development: Tolkien seems to have coined this word to explain names like Neldoreth. Its most obvious precursor is ᴱQ. neldor (QL/65).
boron
noun/adjective. steadfast; trusty man, faithful vassal
A word meaning “steadfast, trusty man, faithful vassal” developed from the primitive form ᴹ✶bóron- (Ety/BOR). Because the initial syllable was stressed in the primitive form, the initial [bor-] did not reduce to [br-] as it did when the primitive vowel was unstressed. The glosses seem to indicate that it could be used as an adjective “steadfast” or a noun “trusty man, faithful vassal”. However, it is possible that the first part of the gloss is meant to read “steadfast/trusty man”, so that the word is only a noun.
ngorthin
adjective. horrible
tóril
noun. queen
A noun meaning “valiant man, warrior” developed from primitive ᴹ✶berō (Ety/BER) after the primitive final vowel vanished in Ilkorin.
