乖

• ピンイン: guāi
• 漢字の分解: 乖 = 北 (back-to-back; diverge) + 屮 (sprouting plant) — ancient pictograph suggesting divergence; semantic shift led to current meaning of 'compliant' or 'well-behaved'

意味

（子どもが）おとなしい；いい子だ

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.

例文

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。
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。
