单身英语怎么说

单身的英文可以说是"single"。这个词来源于拉丁语的"singulus"，意思是"唯一的"或"独特的"。例句如下：

I'm single and ready to mingle.
She's been single for a while now.
He's been single since his divorce.

需要注意的是，"single"还可以表示"单一的"或"单一种类的"。例如：

She's a single mother.
The book is bound in single sheets.
The store only sells single-origin coffee.

如果您想表达"单身"的意思，可以使用"unmarried"，它的意思是"未婚的"。例句如下：

He's an unmarried man.
She's an unmarried woman.
They're an unmarried couple.

需要注意的是，"unmarried"不一定指"单身"，因为它只表示未经正式婚姻仪式结婚的状态。例如，某人可能已经有了同居伴侣，但由于没有结婚，他们仍然可以被称为"unmarried"。
