It’s e it isn’t are short forms of it is e 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).
