妹妹用英语怎么说？

中 → 英 · 家庭

younger sister

妹妹的英文是 younger sister，指比自己小的同辈女性手足。英语必须用 younger 标明长幼，只说 sister 无法体现姐姐还是妹妹。

详解

妹妹译为 younger sister，与 older sister（姐姐）相对。口语中也可说 little sister，但正式场合用 younger sister 更准确，因英语需靠 older/younger 区分排行。

My younger sister is still in high school, and she wants to study medicine.

我妹妹还在上高中，她想学医。

He often takes care of his younger sister when their parents are at work.

父母上班时，他经常照顾妹妹。
