career: [16] Originally, a career was a ‘road or racetrack for vehicles’. Its ultimate source was Latin carrus ‘wheeled vehicle’ (from which we get car), which produced the Vulgar Latin derivative *carāria ‘track for wheeled vehicles’. This passed into English via Proven?al carreira, Italian carriera, and French carrière. Its earliest meaning was ‘racecourse’, and hence, by extension, ‘swift course’; the main present-day sense ‘course of someone’s working life’ did not develop until the 19th century, probably owing to renewed influence of French carrière. => car
career (n.)
1530s, "a running (usually at full speed), a course" (especially of the sun, etc., across the sky), from Middle French carriere "road, racecourse" (16c.), from Old Proven?al or Italian carriera, from Vulgar Latin *(via) cararia "carriage (road), track for wheeled vehicles," from Latin carrus "chariot" (see car). Sense of "course of a working life" first attested 1803.
career (v.)
1590s, "to charge at a tournament," from career (n.). The meaning "move rapidly, run at full speed" (1640s) is from the image of a horse "passing a career" on the jousting field, etc. Related: Careered; careering.
