时刻

时刻 refers to a specific moment or time, often emphasizing significance or urgency. It can imply an important point in time, as opposed to just a general period of time.

The character 时 (shí) means 'time,' and 刻 (kè) originally meant 'to carve' but came to signify 'a moment' or 'a short period.' Together, they form a term that emphasizes a precise, meaningful instant.

时刻 is commonly used in both formal and informal contexts, such as in speeches, literature, or daily conversations. It can also be part of expressions like 时刻准备着 (shíkè zhǔnbèizhē, 'always prepared') or 时刻关注 (shíkè guānzhu, 'keep an eye on').
