It’s and it isn’t are short forms of it is and 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 is the short form of it is. We use 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 is the short form of it is not. We use 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 before 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'.

Giving Short Answers with 'It Is' / 'It Isn't'

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

  • For 'Yes': Yes, it is.
  • For 'No': No, it isn't.

It is important to use the full form it is in positive short answers. Do NOT use Yes, it's.

Summary of 'Be' Forms for 'It' and 'They'

Common mistakes for Spanish speakers

Spanish speakers often make these mistakes:

  • Omitting 'it': In Spanish, you can often leave out the subject pronoun. In English, you must always use it when talking about a thing, animal, or idea.
    Is good.
    It's good.
  • Using 'is' without 'it' in questions:
    Is in Canada?
    Is it in Canada?
  • Using contractions in positive short answers:
    Yes, it's.
    Yes, it is.

Frequently asked questions

When do I use 'it's' and when do I use 'its'?

It's is a contraction of it is or it has. For example, It's a book. Its is a possessive pronoun, meaning 'belonging to it'. For example, The dog wagged its tail.

Can I use 'it' for a baby?

Sometimes, people use it for a baby if they don't know the baby's gender. For example, It's a beautiful baby! However, it's more common and polite to use he or she if you know the gender, or they if you don't.

Is 'it's not' the same as 'it isn't'?

Yes, it's not and it isn't mean exactly the same thing. Both are common in spoken and informal written English. For example, It's not cold and It isn't cold are both correct.
