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.
vilya
noun. (lower) air
vilna
place name. (lower) air
yar i vilya anta miqilis
to whom the air gives kisses
ilma
noun. air
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.
Innermost layer of air in the earliest Lost Tales (LT1/65), given as a derivative of the root ᴱ√VILI in the Qenya Lexicon, along with a variant form Vilya (QL/101). This second form reappeared decades later in The Lord of the Rings as Q. vilya “air, sky” (LotR/1123).
