乖

• Pinyin: guāi
• Hanzi breakdown: 乖 = 北 (back-to-back; diverge) + 屮 (sprouting plant) — ancient pictograph suggesting divergence; semantic shift led to current meaning of 'compliant' or 'well-behaved'

Meaning

Well-behaved; obedient; good. Primarily used to describe a child who is compliant, quiet, and easy to manage. Also used as an affectionate term between close people.

Primarily used to praise children for being well-behaved and obedient. Can also be used affectionately between couples or parents and grown children as a term of endearment. In adult contexts outside close relationships, it may carry a slightly ironic undertone suggesting someone is overly compliant or naive. 乖乖 is a warm reduplication.

Examples

1. 孩子在爷爷奶奶家特别乖，从不哭闹，让两位老人十分省心。 The child is especially well-behaved at his grandparents’ house—he never cries or makes a fuss, which makes things much easier for the two elders.
2. 小猫刚洗完澡，乖乖地蜷缩在大毛巾里，一动不动，安静极了。 Right after its bath, the kitten curled up obediently in a big towel, not moving at all—so quiet and still.
3. 她平时话不多，行事低调，同事们都觉得她很乖，从不惹麻烦。 She doesn’t talk much and keeps a low profile; her coworkers all think she’s very easygoing and never causes trouble.

Don't Say
