Distinguishing ‘里(lǐ)’ and ‘外(wài)’: Prepositions for Location in Chinese

Understanding the subtleties of a language can often be a window into its culture and way of thinking. In Mandarin Chinese, two such words that open up a world of cultural and linguistic understanding are ‘里’ (lǐ) and ‘外’ (wài). Both terms are prepositions of location or place, but their usage and connotations can differ significantly.

The Basic Meanings

  • 里 (lǐ): This character primarily means “inside” or “within.” It indicates a location that is inside a boundary or an area. For example, 在家里 (zài jiā lǐ) means “at home” or “inside the house.”
  • 外 (wài): On the other hand, 外 means “outside” or “external.” It is used to indicate something that is outside a boundary or a limit. For instance, 学校外 (xuéxiào wài) means “outside the school.”

Grammatical Considerations

  • Structure: When used in sentences, ‘里’ and ‘外’ often follow the noun they are modifying. For instance, ‘教室里’ (jiàoshì lǐ – inside the classroom) or ‘门外’ (mén wài – outside the door).
  • Compound Prepositions: Both can form compound prepositions with other characters, like ‘里面’ (lǐmiàn – inside) and ‘外面’ (wàimiàn – outside), to emphasize the location aspect.

里 (lǐ):

    • 我在图书馆里学习。 (Wǒ zài túshūguǎn lǐ xuéxí. – I am studying inside the library.)
    • 这个秘密我只在心里知道。 (Zhège mìmì wǒ zhǐ zài xīn lǐ zhīdào. – This secret, I only know it in my heart.)

外 (wài):

    • 他站在房子外等我。 (Tā zhàn zài fángzi wài děng wǒ. – He is standing outside the house waiting for me.)
    • 这种情况在公司外很少见。 (Zhè zhǒng qíngkuàng zài gōngsī wài hěn shǎojiàn. – This kind of situation is rarely seen outside the company.)


Understanding the nuances of ‘里’ and ‘外’ in Chinese is more than learning prepositions; it’s about grasping the cultural and conceptual frameworks that underlie the Chinese language. These words offer insight into how spaces and relationships are perceived and articulated in Chinese culture, making them indispensable for anyone looking to deepen their understanding of the language and its speakers.
