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.

er

morion
masculine name. the Dark One
Another name for Melko in the poem Fíriel’s Song from the 1930s (LR/72), possibly a combination of the stem form mori- of more “dark” and some variation of the agental suffix -ndo.
Conceptual Development: This name also appeared in the Qenya Lexicon from the 1910s, where it was glossed “Son of the Dark” (QL/62), a combination of the root ᴱ√MORO “dark” and some form of yondo “male descendant”.

etingul
proper name. one of Noldorin race who remained in Kor
A term for the Noldor who remained in Valinor appearing only in linguistic notes from the 1930s (PE21/33), its initial element is derived from primitive ete “back, below”.
ine
pronoun. the one who, the one that
oi-
verb. to live, pass one’s days
tolu-
verb. to stand up, get up, leave one’s seat
A verb in the Quenya Verbal System (QVS) from 1948 given as an example of the inceptive use of the verbal extension *u* (PE22/114), clearly based on the root ᴹ√TOL (Ety/TOL²).
Conceptual Development: In the Qenya Lexicon, ᴱQ. tolu- was glossed “roll up, furl” under the early root ᴱ√TOL+U of similar meaning, contrasted with ᴱQ. velu- “unfurl” (QL/94).
Neo-Quenya: In Tolkien’s later writings it seems tar- became the usual verb for “stand”, but I would retain inceptive ᴹQ. tolu- “stand up, get up” for the sake of variety.
vorongandele
noun. continual repetition, (lit.) harping on one tune
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
A correlative appearing in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/107), a combination of ᴹQ. sa “that [anaphoric]” and ᴹQ. atwe “one of two”.
