Meanings

Adjective

  1. not good enough, proper, or allowed to be accepted

Beyond the definition

Imagine offering your friend a beautifully baked cake, only for them to cut a slice and find that it is completely raw in the middle. They would likely wrinkle their nose and say it is "unacceptable." This word means something is not good enough, breaks a rule, or cannot be allowed. It shows that a clear line has been crossed. A behavior can be unacceptable, a condition can be unacceptable, and even an excuse can be unacceptable. Think of it as a firm "no." If your boss asks you to lie for them, that request is unacceptable.
