文凭用英语可以翻译为"diploma"。它来源于拉丁语，原意是"一张双面的纸"，后来引申为"文件、证书"的意思。

例句：

She was proud to receive her college diploma after years of hard work. （她为在多年努力后获得大学文凭而感到自豪。）

The diploma was presented to him by the dean of the university. （文凭由大学校长颁发给他。）

The diploma is a formal document attesting to the fact that the recipient has completed the requirements of a particular course of study. （文凭是一种正式文件，证明收件人已经完成了特定课程的要求。）
