• knickers

  British word for underwear worn specifically by women and girls; more specific than pants, common in everyday and lingerie contexts, and normally used only in the plural.

In British English, pants and knickers both mean underwear. Pants is gender-neutral, the ordinary word for underwear worn by anyone. Knickers is more specific, meaning underwear worn by women and girls, usually used only in plural. Not compared: pants meaning 'trousers' in American English.

这两个词在英式英语里都指贴身内裤，含义相近，容易混淆；区别在于「pants」是不分性别的通用说法，而「knickers」专指女性内裤，语气上更具体、也更偏日常。这里不比较「pants」在美式英语中表示裤子的用法。
