Other forms: coughs, coughed, coughing
A cough is that sharp bark from the throat when something is in the way — dust, smoke, a crumb gone down the wrong hole, or a chest full of a cold. You feel it building during the quiet part of a concert, you try to hold it in, and out it comes anyway.
Cough is a verb and a noun in equal measure: you cough, you have a cough, and the cough hangs about for a fortnight after the rest of the cold has cleared. It brings a small shelf of vocabulary with it — cough medicine, cough sweets, a dry cough, a chesty cough. An engine coughs too, when it turns over and fails to catch. And there is the informal cough up, which is what you do when somebody finally makes you hand over money you were hoping to keep. Then the spelling: cough looks like though and bough and rhymes with neither. It rhymes with off.

Cough goes back through Middle English coughen to Old English cohhian and a Proto-West Germanic root *kuh-, to cough. Past that the record stops with a single word: onomatopoeic. There is no older story, because the word is the noise itself, written down. Only the letters have drifted since.
