Its not uncommon that you walk on the street you see there are big malls hanging big billboard containing only "Sale". Sometimes, Summer Sale, Winter Sale. In every case you get XX% price off there.
If I ask you Hey, is there any sale running on Nike? what do you think?
- I asked you if Nike is currently selling products. -- well they always sell. So whats the point of this question then?
- I asked you if Nike is currently selling products with discount. -- this might be a meaning.
I am not asking you to provide the meaning from dictionary. I know that. I just want to know the interpretation of that question to most people. In fact the practical meaning of Sale.
