Accepted Answer

Countable nouns (what we can count)	Uncountable nouns (what we can't count)
a/an + countable nouns in the singular: a banana some + countable nouns in the plural: four/some bananas	some milk (NOT: a milk)

Explanation:

Countable nouns are nouns that can be counted. They have a singular and a plural form. We can use "a/an" with singular countable nouns and "some" or numbers with plural countable nouns.
Uncountable nouns are nouns that cannot be counted as individual items. They are often liquids, powders, or abstract concepts. We usually use "some" with uncountable nouns, and we don't use "a/an".
