To be baffled means to feel completely confused or puzzled by something you can't figure out. When you're baffled, you've hit a mental wall: you look at a problem or situation and just can't make sense of it, no matter how hard you try.

A detective might be baffled by a mystery with no clear clues. A student could be baffled by a math problem that seems impossible to solve. Scientists are sometimes baffled when experiments produce unexpected results they can't explain. The word captures that specific feeling when your brain seems to stop working because something just doesn't add up.

You might say “I'm completely baffled” when you can't understand why your friend is suddenly angry, or when you read the same paragraph three times and still don't get it. The word suggests you've really tried to understand, but the answer remains just out of reach.

Something that baffles you is baffling. A baffling riddle stumps everyone who tries it. The good news? Being baffled is often the first step toward real learning. When something baffles you enough to keep thinking about it, you're on your way to a breakthrough.
