chipper
Cheerful, lively, and full of happy energy.
Chipper means cheerful, energetic, and upbeat, especially in a lively, sometimes almost bouncy way. When someone walks into school on Monday morning looking chipper despite the early hour, they're smiling, chatting enthusiastically, and seem genuinely happy to be there. A chipper person often has a spring in their step and an optimistic attitude that can be contagious.
The word often describes people who are noticeably upbeat when others might not be. A chipper waiter stays friendly and energetic even during a busy dinner rush. Your mom might be annoyingly chipper at 6 AM when you'd rather sleep, singing while she makes breakfast and acting like morning is the best time of day.
Sometimes people use chipper with a hint of irony. If your friend says, “You're awfully chipper today,” after you've been grumpy all week, they're noticing the contrast. The word can occasionally sound a bit much, suggesting someone whose cheerfulness feels over-the-top, but usually it's simply a friendly way to describe genuine good spirits and positive energy.
