Quizzical describes a puzzled, questioning expression that shows gentle confusion or curiosity. When your teacher explains a complicated math problem and you tilt your head with a quizzical look, you're showing that you're trying to understand but something doesn't quite make sense yet.

A quizzical expression often involves slightly raised eyebrows, a small frown, or a sideways glance. It's the face you make when your friend tells you an unbelievable story and you're thinking, “Really? Are you sure about that?” Picture a dog cocking its head when hearing a strange sound: that's a quizzical look.

The word suggests friendly puzzlement rather than angry confusion. If your dad gives you a quizzical smile when you claim you've finished all your homework in five minutes, he's gently questioning whether that's really possible. A scientist might look quizzically at unexpected results from an experiment, interested and curious rather than frustrated.

People also use quizzical to describe teasing questions. When someone asks quizzically whether you really ate that entire pizza yourself, they're playfully doubting your claim while giving you a chance to explain.
