过于自大用英语怎么说

过于自大可以用英语表示为 "arrogant" 或 "conceited"。
"Arrogant" 来源于拉丁语 "arrogare"，意思是 "claim or assert as one's own right or possession"，即 "声称或断言为自己的权利或所有物"。"Conceited" 来源于拉丁语 "concinnus"，意思是 "well-arranged, handsome"，后来引申为 "having a high opinion of oneself"，即 "对自己有很高的看法"。
下面是一些英文例句及其中文翻译：
He's so arrogant that he thinks he's always right. 他太自大了，认为自己总是对的。
She's so conceited that she can't stand anyone else being better than her. 她太自大了，不能容忍别人比她更优秀。
His arrogant behavior made him unpopular with his colleagues. 他的自大行为使他在同事中不受欢迎。
She was so conceited that she didn't even try to hide her disdain for others. 她太自大了，甚至没有试图掩饰对别人的蔑视。
