It may sound like a silly question but I am a bit confused about the usage/meaning of paper towel. According to the dictionary, a paper towel is ONE sheet of paper. So if you want to refer to a whole roll you would say "paper towels"? I cannot understand why it makes sense to use it in the following ways:
- a piece of paper towel (is this still a sheet?, an alternate way to say just "paper towel"?)
- From a series (TAAHM): Q: Do you know where your uncle keeps the paper towels? A: I think there IS some up there. (Why is he using IS when he is referring to paper towelS?).
Thanks for any help.
