如果您想询问优惠的英文单词，我们可以说 "discount" 或 "deal"。这两个词都可以表示优惠，只是用法略有不同。

"Discount" 指的是优惠价格，表示对于原价而言，打折后的实际支付金额。例如：

I bought a new shirt on sale. It was originally $20, but I got a 20% discount, so I only paid $16.
The store is offering a 10% discount on all clothing this week.

"Deal" 则指的是优惠条件，表示在满足一定条件的情况下，享受更优惠的条件。例如：

I found a great deal on a hotel room for my vacation. It's only $100 per night, and it includes free breakfast and free parking.
The restaurant is offering a deal where you can get a free dessert with the purchase of a main course.

两个词都来源于拉丁文，"discount" 源自 "discountus"，"deal" 源自 "dipgere"。
