This word is often used in the phrase “copse of trees,” but that’s redundant — “copse” means “a small group of trees.” The etymology of this word is roundabout; it comes from “coppice,” a Middle English word meaning “to cut back a tree or shrub to encourage new growth,” and as a noun it’s the area where that took place. Its Latin root is “colpus,” which means “a blow” (as in “come to blows”). “Copse” developed as a word for the new growth and trees that resulted from a coppice.
