Cough [Noun] Webster's Dictionary 1828

A violent effort of the lungs to throw off offending matter; a violent, sometimes involuntary, and sonorous expiration, suddenly expelling the air through the glottis. The convulsion of the muscles serving for exspiration gives great force to the air, while the contraction of the glottis produces the sound. The air forced violently carries along with it the phlegm or irritating matter which causes the convulsion or effort of the muscles.
