曾经

• Pinyin: céng jīng
• Hanzi breakdown: 曾 = a layered structure suggesting 'layers of the past'; 经 = 纟(silk) + 巠 (phonetic), originally meaning warp threads, extended to 'pass through'

Meaning

Once; formerly; previously. Indicates that something happened at some point in the past.

An adverb placed before the verb to indicate past experience or a former state. Similar to English 'once' or 'used to.' Often paired with 过 to emphasise completed past experience. More literary than simply using 过 alone.

Examples

1. 我曾经在北京住过三年。 I once lived in Beijing for three years.
2. 她曾经是一名老师，后来成了作家。 She was once a teacher and later became a writer.
3. 这里曾经是一片森林，现在变成了城市。 This place was once a forest, but now it has become a city.
