"因为"的同义短语英语是 "because"。

"Because" 来源于古英语中的 "þæt" 和 "by" 的结合,最初是 "þæt" 和 "by" 两个单词的合并,后来变成了 "bycause",最终变成了现在的 "because"。

下面是一些英文例句及其中文翻译:

I'm late because I overslept. (我迟到了,因为我睡过头了。)
She couldn't come to the party because she was sick. (她不能参加聚会,因为她生病了。)
He failed the exam because he didn't study enough. (他考试不及格,因为他没有足够的学习。)
