Momentary means lasting only a very short time — a blink, a flash, then gone. A momentary pause, a momentary look of surprise, a momentary loss of power. It is a calm, slightly written adjective: you will hear it in news and careful speech more than in playground talk. It does not mean “important.” Though actually, momentary and momentous both start from moment, and that is why they trick the eye. Here moment is the short stretch of time. A momentary decision would be a decision that lasted a second, not a decision that changed your life.
片刻的；瞬間的
組成moment (a very short time) + -ary (turns it into an adjective: “of a moment”). From Late Latin mōmentārius “of brief duration,” from mōmentum “a short time, an instant.”

- Yet oh! what an immense difference did I feel between this impression of a pleasure merely animal, and struck out of the collision of the sexes by a passive bodily effect, from that sweet fury, that rage of active delight which crowns the enjoyments of a mutual love-passion, where two hearts, tenderly and truly united, club to exalt the joy, and give it a spirit and soul that bids defiance to that end which mere momentary desires generally terminate in, when they die of a surfeit of satisfaction!
