Example of an idiom: "Break a leg"

Meaning: This idiom is commonly used in the performing arts industry, particularly in theater. It is used to wish someone good luck before a performance. However, the literal meaning of "break a leg" is the opposite of what is intended. It is believed that saying "good luck" before a performance is considered bad luck, so instead, performers say "break a leg" as a way to wish each other success without actually saying the words "good luck."
