Peachy means wonderful, perfect, or just fine. When your teacher asks how your day is going and you say “Everything's peachy!”, you're saying things are going well. The word comes from the idea that a ripe, sweet peach represents something delightful and satisfying.

You'll often hear peachy used cheerfully: “We finished our project early, so everything's peachy.” But listen carefully to the tone, because people sometimes use it sarcastically when things are actually going wrong. If your friend trips, drops their lunch tray, and mutters “Just peachy,” they obviously mean the opposite. The sarcastic use has become so common that you need context to know whether someone really means things are good or they're frustrated and joking about how bad things are.

The phrase peachy keen means the same thing but sounds even more old-fashioned and enthusiastic, like something from a 1950s movie. Whether used sincerely or sarcastically, peachy adds personality to how we talk about whether things are going well or falling apart.
