"He eats mushroom."
Translation:Anh ấy ăn nấm.
I'm getting a wee bit confused. Why no classifier here? I thought food required one in such sentences or did I miss a note about that?
Classifier is for countable nouns.
Mushroom is both a countable and uncountable noun. ""Eats mushroom" suggests it's uncountable in this case and therefore, no classifier.
