Understanding "不时" - Chinese Word Explanation

1. Basic Information

• Word: 不时
• Pinyin: bù shí
• Literal Meaning: not time / without a fixed time
• Primary Meaning: from time to time; now and then; every so often

2. In-depth Explanation

• Context and Usage:
  不时 is an adverb used to describe an action that occurs repeatedly but at irregular intervals — it is not constant, yet not rare. It can be translated as “from time to time,” “now and then,” “every so often,” or even “frequently” in a loose sense, but it always carries the nuance of unpredictable timing. Unlike 经常 (jīngcháng), which implies a high frequency and some regularity, 不时 suggests something pops up sporadically, giving a more casual, intermittent feel.

You will find 不时 in both spoken and written Chinese. It most often appears right before a verb (or a verb phrase), optionally followed by the adverbial marker 地 (de). Whether you use 地 or not, the meaning remains the same.

Important note: 不时 is not used to talk about things that happen on a fixed schedule. For example, “I go to the gym every Monday” would not use 不时; that would call for 定期 (dìngqī, regularly) or a specific time phrase.

• Character Breakdown:
• 不 (bù) – “not,” a basic negation character.
• 时 (shí) – “time,” “moment,” or “hour.”

Together the two characters literally mean “not (at a fixed) time.” When an event does not have a set moment to happen, it happens irregularly — or from time to time. This literal image helps you remember why 不时 carries the meaning of sporadic repetition.

2. Chinese: 那个小孩在公园里跑来跑去，不时发出快乐的笑声。

Cultural Notes

While 不时 today is primarily used as the common adverb described above, learners may also encounter the classical phrase 不时之需 (bù shí zhī xū). Here 不时 takes on a slightly different meaning: “unexpected” or “unforeseen,” and the whole expression means “provision for unexpected needs” — something like “a rainy-day fund” in English. This is a fixed literary expression and not an example of the everyday adverbial usage. Understanding it, however, can help you appreciate how the core idea of “not fixed time” extends to “unexpected.”

Conclusion

To remember 不时, think of “no set time” → something that happens irregularly, from time to time. Use it before verbs to describe actions that recur at unpredictable moments. With just two simple characters, 不时 gives your Chinese a natural, native-like way to express the idea of “now and then.”
