Other forms: wasted; wasting; wastes
If waste is useless, then to waste is to fritter away. Don't waste time putting your waste paper in the waste basket, just chuck it in the recycling bin.
As a noun, waste, meaning “desolate regions” stems from the Old English westen, meaning “a desert, wilderness.” Later, it came to imply a “useless activity,” and even later than that, “refuse matter,” or “trash.” As a verb, waste “devastate, ruin,” comes from the Latin vastare, “to lay waste.” It later adopted the sense of “spend or consume uselessly.” It can also mean “to kill.” The poet E. E. Cummings said, “The most wasted of all days is one without laughter.”
