反身代詞是一種表示反射或強調的代詞。它的基本含義是：通過反身代詞指代主語，使施動者把動作在形式上反射到施動者自己。因此，反身代詞與它所指代的名詞或代詞形成互指關係，在人稱、性質、數上保持一致。
反身代詞經常和介詞有一些重要的搭配，接下來讓我們來看看這些例子吧!
to oneself
該搭配的基本意思是“獨自地”“單獨地”“給自己用”，通常與某些動詞配合使用，其含義也往往受所搭配動詞意思的影響。如：
1. cry to oneself 哭著對自己說
Oh Ned, Nancy cried to herself, why did you have to leave me? 哦，內德，南希還哭著對自己說，你為什麼一定得離開我呢?
2. have something to oneself 獨自享用某物
I have the whole day to myself. 今天整天都是屬於我自己的。
among oneself
該搭配中的反身代詞通常為ourselves, themselves，且通常與動詞agree, argue, quarrel, decide, divide, talk 等搭配，表示“彼此”“互相”“……之間”之類的意思。如：

between ourselves
該搭配為英語中的固定短語，意思是“勿與外人道私下說的話”“咱們私下說說(不足為外人道)”等，在具體語境中通常可以有比較靈活的翻譯。如：
