Origin & History of “choke”

Etymologically, to choke is to cut off air by constricting the ‘cheeks’, for it is a derivative of cēoce, the Old English word for ‘cheek’. there is actually such a verb recorded, just once, from Old English: the compound ācēocian, with the intensive prefix ā-; so probably the simple verb existed too, though evidence for it has not survived. The noun sense ‘valve controlling the flow of air to an engine’ dates from the 1920s, but it was a natural development from an earlier (18th-century), more general sense ‘constriction in a tube’; its parallelism with throttle, both being applied to constriction of the air passage and hence to control valves in an engine tube, is striking. (The choke of artichoke has no etymological connection with choke ‘deprive of air’.).
