temerity

This term describes a specific type of boldness that is perceived as reckless or presumptuous. It carries a strong negative connotation, suggesting that the person acting has overstepped a social or professional boundary and lacks the proper respect for authority or danger. Because it refers to an abstract quality of behavior, it is an uncountable noun. It cannot be pluralized and does not take a numerical count; instead, it is typically measured by adjectives like great, sheer, or utter.
