In English, some nouns are countable (we can count them) and some are uncountable (we treat them as a mass or whole). Knowing which is which helps you use the correct form of the verb, article, or quantifier.
Countable nouns are things you can count: one, two, three… They have singular and plural forms, and we can use numbers or “a/an” in front of them.
You can use words like a, an, many, a few, several, how many with countable nouns.
Uncountable nouns are things we don’t count individually. They are usually substances, concepts, or collective categories. They only have one form (no plural).
You can’t say ❌ “an advice” or ❌ “informations.” Instead, use a quantifier like:
Use words like some, a little, much, a bit of, how much with uncountable nouns.
To talk about a single idea or unit of an uncountable noun, use phrases like a piece of, an item of, a bit of
