Translation guide
The English word "audacious" can mean bold and daring, or shockingly disrespectful. Japanese has different words for these nuances, and context is key.
Describing someone or an action that is brave, adventurous, or willing to take risks, often in an impressive way.
The most common and versatile word for 'bold' or 'daring'. Can be used positively for courageous actions or plans.
Describing behavior that is rude, insolent, or shows a lack of respect, often in a surprising way.
大胆 (daitan) is usually positive or neutral, meaning 'bold' or 'daring'. 厚かましい (atsukamashii) is negative, meaning 'shameless' or 'impudent'. Using 大胆 for a rude action will sound like you are praising the boldness, not criticizing the rudeness.
