Give an example of a fixed expression and explain its meaning.

One example of a fixed expression is "break a leg." This phrase is commonly used in the performing arts industry to wish someone good luck before a performance. Despite its literal meaning being negative, the phrase is used to convey a positive message. It is believed to have originated from the superstition that wishing someone good luck directly would bring them bad luck, so saying the opposite would actually bring them good luck.
