God, it’s maddening. “I have several cheeses in my fridge” vs. “this is the cheese aisle of my Kroger.” I know it has something to do with countability, but there’s no way I could explain to a foreign speaker how this shit works. No one learns this “cheese: plural” vs. “cheeses: plural” shit in school, we just know it, and no one ever thinks twice about it, despite the fact that it’s incredibly subtle.
