Brazen means shamelessly bold, often in a way that shows no embarrassment about doing something wrong or inappropriate. When someone acts in a brazen way, they're not sneaky or subtle. They do what they want openly, even when they know others disapprove.

Imagine a student who copies answers during a test while making direct eye contact with the teacher, not even trying to hide it. That's brazen behavior: bold, shameless, and shocking in its openness. A brazen lie is one told confidently, without hesitation or guilt. A brazen thief might walk into a store and take something right in front of everyone, acting as if they have every right to do so.

The word often carries a sense of surprise or outrage. When we call something brazen, we're usually expressing disbelief at someone's nerve. “I can't believe she had the brazen audacity to ask for extra credit after skipping half the classes!”
