"Discount" 来自拉丁文 "discountus"，意思是 "to deduct" 或 "to subtract"。"Sale" 是 "to sell" 的过去分词。所以 "discount sale" 的意思就是 "减价销售"。
"On sale" 则来自 "on" 意思是 "在"， "sale" 意思是 "销售"，所以 "on sale" 的意思就是 "正在销售中"。
例句:
The store is having a discount sale on winter coats.
(商店正在举行冬季大衣打折销售)
I got this dress on sale for 50% off.
(我以五折的价格买到了这件连衣裙)
Everything in the store is on sale today.
(商店里的所有东西今天都正在销售中)
