原价的英语说法是 "original price"。来源是原价的本义是原先的价格，即商品刚刚上市时的价格。例句如下：

The original price of this dress was $100, but it's on sale now for $50.

此裙子的原价是 $100，但现在打折了只要 $50。

你可以用 "list price" 或 "manufacturer's suggested retail price" 来指代原价。这些说法都与原价有关，但它们的来源和概念略有不同。例句如下：

The list price of this car is $20,000, but I'm sure we can negotiate a better price.

这辆车的挂牌价是 $20,000，但我相信我们可以谈判一个更好的价格。

The manufacturer's suggested retail price of this laptop is $1,500, but I bought it on sale for $1,200.

这台笔记本电脑的厂商推荐零售价是 $1,500，但我打折买的只要 $1,200。
