check (n.) Look up check at Dictionary.com

c.1314, from O.Fr. eschequier "a check at chess," from eschec, from V.L. *scaccus, from Ar. shah, from Pers. shah "king," the principal piece in a chess game (see shah). When the king is in check a player's choices are limited. Meaning widened from chess to general sense of "adverse event, sudden stoppage" and by c.1700 to "a token used to check against loss or theft" (surviving in hat check) and "a check against forgery or alteration," which gave the modern financial use of "bank check, money draft" (first recorded 1798), probably influenced by exchequeur. Check-up "careful examination" is 1921, Amer.Eng., on notion of a checklist of things to be examined.

So it looks like cheque was the original?
