Couch vs. Cough — What's the Difference?

A couch, also known as a sofa, settee, futon, or chesterfield (see Etymology below), is a piece of furniture for seating two or three people. It is commonly found in the form of a bench, with upholstered armrests, and often fitted with springs and tailored cushions.

A cough is a sudden expulsion of air through the large breathing passages that can help clear them of fluids, irritants, foreign particles and microbes. As a protective reflex, coughing can be repetitive with the cough reflex following three phases: an inhalation, a forced exhalation against a closed glottis, and a violent release of air from the lungs following opening of the glottis, usually accompanied by a distinctive sound.Frequent coughing usually indicates the presence of a disease.
