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. Expressions play a crucial role in communication, as they enrich language and allow speakers to convey complex thoughts and feelings effectively.

Example

“ Bite the bullet ” is an expression that means to endure a painful experience with courage.

“咬紧牙关”是一个意味着勇敢承受痛苦经历的表达。
