A bonus is extra money or a reward given in addition to what is usual or expected. It can also mean any extra good thing that comes as a pleasant surprise.
It comes from Latin “bonus,” meaning “good,” and entered English in the 18th century through business language. It originally referred to an extra dividend or payment.
The word is so positive that we use it casually: “The weather was nice, and as a bonus, there were no crowds.” It shows how humans love the idea of “more than expected,” whether it’s money, time, or dessert.
