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.

Doriathrin

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.

masculine name. *Steadfast Star

An earlier name for S. Eluréd (LR/147). It appeared in The Etymologies containing Ilk. boron “steadfast”, but the name were rejected, probably at the same time as the name of his brother Ilk. Elbereth (Ety/BOR). Its initial element might be el “star”.
