易错句子The baby weaned at six months.
正确表达The baby was weaned at six months.
wean 是及物动词，主语通常是母亲或照顾者，婴儿是承受者，所以要用被动语态。汉语可以说“婴儿断奶了”，但英语不能说 the baby weaned，而要说 the baby was weaned。

易错句子She is trying to wean her son video games.
正确表达She is trying to wean her son off video games.
表示“使某人戒除某物”时，结构是 wean someone off/from something，戒除的对象要用 off 或 from 引出，不能直接跟在某人后面。
对应“使断奶”义：wean 指逐渐停止母乳喂养，breastfeed 指用母乳喂养，二者动作方向相反；此反义词不适用于“使戒除习惯”的引申义。
wean 与 wane 拼写相似、读音相近，但含义完全不同：wean 指“使断奶”或“使逐渐戒除习惯”，wane 指“逐渐减小、减弱”（如月亏）。表达“戒掉”时用 wean，表达“减退”时用 wane。
wean 与 ween 发音完全相同（/wiːn/），但意思毫无关联：wean 是“使断奶/使戒除”，ween 是古旧的“以为、猜想”。现代英语中 ween 几乎只出现在文学作品里，看到它时要想“猜想”，而非“断奶”。
