Translation:Is this shirt discounted?
Is there a word for "on sale?" Because saying on sale is a more natural way than discounted.
I can't exactly answer your question, but I can say that to my mind "on sale" should be accepted, as it's used in essentially the same circumstances.
(However, you may be interested to know that "on sale" for "discounted" is N. Am. usage. In British English it essentially means what North Americans call "for sale".)
N American English should be accepted in the same way as British English. Many sentences in this program though seem to be more in chinglish.
Mss Pancakes, it seems that you are working for the Duo Birdie, if so, can you please revamp the system? Coz, with all the restrictions and so few possibilities of verity of answers, it is quite discouraging in many instances... In short not fun at all....
What comes again and again is the view saying that many answers come as unnatural. Please take this into account as well. In " 很累，it should stay" very tired" in English, both express exactly the same idea.
