It’s et it isn’t are short forms of it is et it is not. We use them to talk about singular things, animals, or ideas. It’s is for positive statements, like It’s a new car. It isn’t is for negative statements, like It isn’t old. These forms help you speak more naturally and quickly in English. They are very common when describing objects, places, or situations. Remember to always use it when you are talking about one non-human thing or an idea.

What Does ‘It’ Mean?

It is a pronoun. We use it to talk about:

  • One thing: It’s a book.
  • One animal: It’s a cat.
  • One idea or situation: It’s interesting.

We do not use it for people. For people, we use he (for a man/boy) or she (for a woman/girl).

How Do We Use 'It's'?

It's est l'abréviation de it is. Nous utilisons it's for positive sentences.

  • To describe something: It's big.
  • To say what something is: It's a phone.
  • To talk about the weather: It's sunny.

Using it's makes your English sound more natural, especially in speaking.

How Do We Use 'It Isn't'?

It isn't est l'abréviation de it is not. Nous utilisons it isn't for negative sentences.

  • To say something is not true: It isn't correct.
  • To say what something is not: It isn't a car.
  • To say something is not in a place: It isn't here.

You can also say it's not, which means the same as it isn't. For example, It's not cold.

Asking Questions with 'Is It...?'

To ask a question about a singular thing, animal, or idea, we put is avant it.

  • Is it a new house?
  • Is it expensive?
  • Is it in Spain?

These are 'Yes/No' questions because the answer is usually 'Yes' or 'No'.

When someone asks a 'Yes/No' question with Is it...?, you can give a short answer:
