The Best Chinese Idioms to Sound Smarter
Idioms in English vs. Chinese 成語
The word “idiom” as it relates to English is actually very vague. The Oxford dictionary defines it as “A form of expression, grammatical construction, phrase, etc., used in a distinctive way in a particular language, dialect, or language variety…”. Examples of English idioms include phrases like “turn a blind eye”, “beat around the bush”, and “spill the beans”.
In Chinese, however, the word 成語 (translated as “idiom”) is generally more specific and well defined. 成語 are expressions that are typically four characters long and usually allude to or quote classical Chinese texts in order to refer to specific situations or bits of wisdom. Unlike idioms in English, it’s more common for Chinese speakers to know exactly what text their idioms come from, making them extremely rich in meaning. For this reason, 成語 are usually associated with high culture and history, and using them can make your speaking or writing sound more formal and articulate.
Essentially, English idioms like “it takes two to tango” sound informal and quirky, while Chinese 成語 have the opposite effect. Integrating some Chinese idioms into your vocabulary is essential for becoming a true master of Chinese and sounding smart!
