While I know how to use the words that I use, I do not know if there is a term to describe words that are uncountable nouns, but at the same time are countable in other circumstances. "Cheese" is one example perhaps. I find researching this does not clarify anything - words seem to be countable and uncountable at the same time (depending on context) - is there a term for this or do we just have to accept the context rather than having an overriding term?
Cheese is not countable in any situation.
You can count types of cheese (four cheese pizza), you can even add a unit and say four blocks of cheese. But cheese itself is not countable.
Uncountable nouns CAN be modified by numbers if units of measurement are included.
Also, uncountable nouns can be used in English in the plural to mean "more than one instance (or example) of a certain sort of entity" (refer to my four cheese pizza example)...
