To hesitate means to pause before doing something, usually because you feel uncertain or worried about what might happen. When you hesitate before jumping off the diving board, you're standing there for a moment, wondering if you really want to do it. When you hesitate before answering a question in class, you might know the answer but worry you'll say it wrong.

Hesitation happens in that brief moment between deciding to act and actually acting. A chess player might hesitate before moving a piece, thinking through possible consequences. Someone might hesitate before trying a new food, wondering if they'll like the taste. You can hear hesitation in someone's voice when they say “Well... I'm not sure...” with that telltale pause.

Sometimes hesitation protects us: it's smart to hesitate before petting a strange dog or crossing a busy street. But too much hesitation can hold you back from opportunities. The phrase he who hesitates is lost suggests that overthinking can mean missing your chance.

Hesitation isn't the same as simply waiting or being patient. Patience involves calm confidence, while hesitation carries doubt. When you're hesitant about something, you're unsure whether to move forward. Deciding when to hesitate and when to act decisively is part of growing up and gaining confidence.
