choke: [14] 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’.)
c. 1300, transitive, "to strangle;" late 14c., "to make to suffocate," of persons as well as swallowed objects, a shortening of acheken (c. 1200), from Old English aceocian "to choke, suffocate" (with intensive a-), probably from root of ceoke "jaw, cheek" (see cheek (n.)).
Intransitive sense from c. 1400. Meaning "gasp for breath" is from early 15c. Figurative use from c. 1400, in early use often with reference to weeds stifling the growth of useful plants (a Biblical image). Meaning "to fail in the clutch" is attested by 1976, American English. Related: Choked; choking. Choke-cherry (1785) supposedly so called for its astringent qualities. Johnson also has choke-pear "Any aspersion or sarcasm, by which another person is put to silence." Choked up "overcome with emotion and unable to speak" is attested by 1896. The baseball batting sense is by 1907.
