What is an "expression"?

An expression is a word or phrase that conveys a specific idea, emotion, or meaning, often used in a particular context. Expressions can be literal, where the meaning is clear and straightforward, or idiomatic, where the meaning is not obvious from the individual words. For example, the expression "kick the bucket" is an idiomatic phrase meaning to die, which may not be understood by looking at the words alone.
