歇息 (xiē xi) is a compound verb meaning 'to rest' or 'to take a break'. The first character 歇 (xiē) originally meant 'to stop, to pause', and the second character 息 (xī) means 'to breathe' or 'to rest' — together they emphasize a deliberate pause to recover energy. Though both characters share the same pinyin spelling 'xi', note that 息 carries the first tone (xī), not the neutral tone; however, in spoken Mandarin, 息 in this compound is commonly pronounced with a neutral tone (xi) due to tone sandhi in frequent two-syllable verbs.

This word is moderately formal and often used in written Chinese, storytelling, or polite speech — for example, when suggesting rest during travel, work, or after exertion. It’s more literary than everyday colloquial alternatives like 休息 (xiūxi), but still widely understood and appropriate in both spoken and written contexts, especially in northern dialects and standard Mandarin.
