Nouns can be countable  if you can count them (one, two, three...) or uncountable if it's very difficult or impossible to count them. 


  • Countable nouns can be counted,  an orange, two apples, three cars, etc. 
  • Uncountable nouns cannot be counted, milk, rice, water, sugar, etc. 

We use           SOME      (affirmative)         

We use           ANY         ( negative and questions)
