绝交的英语怎么说

绝交的英文可以表达为"break off (a relationship)"。这个词来源于英文动词"to break"，表示"打破"、"折断"，后面加上介词"off"表示"完全地分离"，加上"a relationship"表示"一段关系"，因此可以用来表示"终止一段关系"。

例句：

She broke off the engagement because she realized that he wasn't the right person for her. (因为她意识到他不是她的另一半，所以她终止了婚约。)
They decided to break off their friendship because they had grown apart over the years. (他们决定终止友谊，因为他们随着岁月流逝而分开。)
