Based on another song I wanted to translate, I wanted to see if I could change the verb lhossa "to whisper" into the noun "whisper", like a sound. This is honestly solely because I can't find the Sindarin term for "sigh" as in "a sigh". (also can't find that article but I'll get there eventually)
Alternatively, if there was a reconstructed Sindarin word for the noun "sigh", how would that look?
Unfortunately there is a Neo-Quenya word for “sigh” but the Neo-Sindarin equivalent does not mean the same thing even though they are based of the same root. SIKW as sibra- means “to whimper”.
As for a noun it is lhoss or if using a Verbal Noun lhossad
Verbal Noun (Gerund): This is a noun form of a verb that expresses the action or process of the verb. In Sindarin, the suffix "-ad/-ed (A-stem/I-stem)" is often used to form verbal nouns. For "lhossa-," the verbal noun would be "lhossad," meaning "the act of whispering" or "whispering."
Regular Noun: This would be a noun that refers to the concept or thing related to the verb, but not the action itself. It is as a noun meaning "whisper."
Verbal Noun (Gerund): "lhossad" (the act of whispering)
Regular Noun: "lhoss", "i-thloss", "in lhyss" (a whisper, the whisper, the whispers)
