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.

Quenya

caimassë ("k")noun "lying in bed, sickness" (KAY)
caila
lying in bed, bedridden, sickness
caila ("k")adj.(and noun???) "lying in bed, bedridden, sickness" (KAY, VT45:19). It may be that the gloss "sickness" applies only to the "Noldorin"/Sindarin form cael listed before Quenya caila, since cael could be both an adjective and a noun (the ancient adjective kailā "bedridden" merging with the noun kailē "sickness"). In Quenya the form caila < *_kailā _would probably be an adjective only.
