Articles
💡Remember!
There are two kinds of articles in English: the indefinite article (a/an) and the definite article (the).
We use a / an
- with singular countable nouns when we are talking about them in general.
Example: An ant is a tiny animal.
- after the verbs to be and to have.
Example: I'm a student. / I have an eraser.
We use the
- with singular or plural nouns when we already know them or when they are mentioned for the second time.
Example: The bike in front of her house is nice.
- with nouns which are unique.
Example: The air is dirty.
