Etymology
Origin of cooperate
First recorded in 1595–1605; from Late Latin cooperātus, past participle of cooperārī “to work with”; see co-, operate
Explanation
When you cooperate, you work together. You can cooperate with the police by telling them everything you know about your neighbor’s pet leopard, or your preschooler can cooperate with you by doing everything you tell him to do, now! The verb cooperate is originally from the combination of The Latin prefix co-, meaning “together,” and operari, meaning “to work.” The term “co-op” is a shortening of cooperative and is used when people work together (or cooperate) to run a preschool, health food store, or a residence. When you start or join a co-op, be prepared to cooperate with your partners, and remember: somebody has to clean the bathrooms.
