Which term means bold and without shame?

The term that conveys being bold and without shame is "brazen." This word is often used to describe someone who acts with a lack of concern for what others might think, not hesitating to engage in behavior that may be considered audacious or disrespectful. Individuals described as brazen may show a disregard for social norms or rules, exhibiting a type of confidence that can be seen as shocking or offensive.

In contrast, the other terms have different meanings. "Timid" refers to someone who is shy or lacking in self-confidence, which is the opposite of being bold. "Brash" can mean someone who is aggressive and rude in their boldness, but it doesn't necessarily convey the lack of shame implied by "brazen." "Reserved" refers to someone who is self-restrained and prefers to keep feelings or thoughts private, which does not align with the idea of boldness or shamelessness. Thus, "brazen" is the most accurate term for a person who acts boldly and without shame.
