2. How are countable and uncountable nouns used?

• Countable nouns have singular and plural form. When they are in singular, they can be preceded by the indefinite article a/an.
  I need an umbrella.

  This is a parrot.
• Uncountable nouns only have singular form. They can't be preceded by the indefinite article a/an. They can be preceded by some/any.
  I need milk.
