Origin of saccade

1720–30; <French saccade jerk, jolt, originally, movement of a horseman who abruptly pulls the reins, equivalent to Middle French saqu(er) to pull violently (N dialectal variant of Old French sachier, ultimately derivative of sacsack1, hence presumably with sense “withdraw from a sack”) + -ade-ade1
