以免
How to Understand
以免 is a conjunction used to express the purpose of preventing an undesirable outcome. It often translates to 'to prevent' or 'in order to avoid' in English.
The character 以 (yǐ) originally meant 'to use' or 'by means of,' and it also functions as a conjunction meaning 'in order to.' The character 免 (miǎn) means 'avoid' or 'prevent.' Together, 以免 conveys the idea of taking action to avoid something negative.
It is commonly used in formal and informal contexts, especially when giving advice or explaining precautions. For example, people might say 以免发生事故 (yǐ miǎn fāshēng shìgù) to mean 'to prevent an accident.' Understanding 以免 helps learners grasp how Chinese expresses caution and prevention in daily communication.
