Other forms: xeroxed; xeroxing
When you use a copy machine, you make a xerox. Some college classes require you to buy expensive textbooks, while others provide you with binders full of xeroxes.
The word xerox is trademarked, kind of like Frisbee or Kleenex. The word was coined in the 1950s, from xerography, "printing without the use of liquid chemicals," which has a Greek root, xeros, "dry," and an ending borrowed from photography. You can use xerox as a noun or a verb: "You should xerox your ID and keep a copy of it on file in case you lose your wallet."
