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.
ilverin
masculine name. Littleheart
elwenil(do)
masculine name. Littleheart
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.
Qenya name of the “Gong Warden” of Cottage of the Lost Play (LT1/52), a character that does not appear in Tolkien’s later writings.
Conceptual Development: The name first appeared as ᴱQ. Elwenil(do), a diminutive form of ᴱQ. elwen “heart” (LT1A/Ilverin, LT2/202), a word appearing in the Qenya Lexicon from the 1910s (QL/35, 52). Tolkien apparently revised its etymology, but the revised form of its initial element does not appear, though its Gnomish equivalent does: G. ilf (GL/50).
