Give an example of an idiom and explain its meaning.

One example of an idiom is "break a leg." This phrase is commonly used in the performing arts industry to wish someone good luck before a performance. However, its literal meaning is quite different from its intended meaning. The idiom "break a leg" does not actually encourage someone to physically break their leg, but rather it is a way of expressing encouragement and wishing someone success. It is believed that this idiom originated from the superstition that wishing someone good luck directly would bring them bad luck, so instead, the opposite is said. This idiom highlights the figurative nature of idioms and how their meanings can differ from their literal interpretations.
