Sidenote, because I think this is fascinating:

Just because a noun is a mass word in one language, it doesn't mean it has to be in other languages that have borrowed the word.

For example, in my language, "lego" is a mass word, and to make a plural you would have to say something like "pieces of lego", but in English, the plural of "lego" is "legos".
