Meaning and Usage
The character 外 (wài) primarily means "outside" or "external." It is used to indicate a location outside of a place or boundary. It can function as a noun, adjective, or preposition depending on context.
Common Contexts
- Physical location: describing something outside a building, city, or object (e.g., 城市的外面, 桌子外).
- Abstract or extended meaning: referring to foreign or external things, such as 外语 (foreign language).
Collocations and Patterns
- 外面 (wàimiàn): outside (a place or area), very common in daily speech.
- 公司外 (gōngsī wài): outside the company, showing how 外 can follow a noun to indicate outside of that noun.
- 外语 (wàiyǔ): foreign language, showing a compound where 外 means "foreign" or "external" in a broader sense.
Usage Notes
When used as a location marker, 外 often appears after the noun it modifies (e.g., 桌子外). It can be interchangeable with 外面 but 外面 is more colloquial and often used alone as a noun meaning "outside." 外 is also used in compounds to indicate something external or foreign.
Common Confusion
Don't confuse 外 with 里 (lǐ), which means "inside." They are often paired opposites in spatial descriptions. Also, 外面 is more conversational, while 外 can be more formal or used in compound words.
