Etymology

Origin of operate

First recorded in 1600–10; from Late Latin operātus, past participle of operārī, -āre “to work, be efficacious, effect, produce,” Latin: “to busy oneself,” verbal derivative of opera effort, work, akin to opus “work”; see -ate 1

Explanation

You'll want to find a skilled surgeon to operate on your hand. Once your hand is working again, you'll be able to operate your buzz saw with ease. Operate comes from a Latin root related to opus, "work," and it's a verb that can be used for all kinds of work. Your computer can operate smoothly, the lottery can operate successfully, your school can operate a day care center in some vacant classrooms, and you can operate your vehicle in a safe manner. If you're an unshakable optimist, your friends may say you "operate in a dream world."
