pharyngitis (n.)

"musculo-membranous pouch at the back of the nasal cavities, mouth, and larynx," 1690s, from Greek pharynx (genitive pharyngos) " throat, joint opening of the windpipe," which is related to pharanx "cleft, chasm, gully, deep trench;" all of uncertain origin; Beekes suggests Pre-Greek origin. The combining form is pharyngo-, before vowels pharyng-; the Modern Latin plural is pharynges.
