goal (n.) Look up goal at Dictionary.com
1530s, "end point of a race," of uncertain origin. The noun gol appears once before this, in a poem from early 14c. and with an apparent sense of "boundary, limit." Perhaps from Old English *gal "obstacle, barrier," a word implied by gælan "to hinder" and also found in compounds (singal, widgal); and compare Old Norse geil "a narrow glen, a passage." Or from Old French gaule "a pole," from Germanic; or a figurative use of Middle English gale "a way, course" (mid-14c.) Sports sense of "place where the ball is put to score" is attested from 1540s. Figurative sense of "object of an effort" is from 1540s.
