v.“strangle to death,” c.1400, probably from Middle English throte “throat” (see throat). Related: Throttled; throttling. The noun, in the mechanical sense, is first recorded 1870s, from throttle-valve (1824), but was used earlier as a synonym for “throat” (1540s); it appears to be an independent formation, not derived from the verb.
