用法说明	Use 'external' when referring to things on the outside, like a person's external features. Avoid using it in very casual speech.	Use 'foreign' when describing something from outside your own country. It's common in discussions about travel, culture, or citizenship. Avoid using it in overly informal situations.	Use 'outer' to describe things that are on the outside or surface. It works well in both formal and casual contexts, but avoid using it when discussing something that only exists internally or is deeply hidden.	Use 'outside' when referring to places that are open or not enclosed. Avoid in formal writing where 'external' might be preferable.
