Laryngitis → It is formed from "larynx" (from Greek "larynx", meaning the organ of voice) and "-itis" (from Greek "itis", meaning inflammation). The word "laryngitis" refers to the inflammation of the larynx, which affects voice production.
Think of the 'larynx' as the organ responsible for voice, and '-itis' indicating inflammation — so laryngitis means inflammation of the voice organ.
