本周问题与答案

Fei Yang has emailed us with this week’s question. She wants to know the difference between it’s and its.

It’s

This is two words joined together – usually it and is. The apostrophe takes the place of the i in is. This kind of word is called a contraction.

So you could say it’s hot today, which is the contracted form of it is hot today.

	It’s hot today

Other contractions are things like I’ll (I will), he’d (he would) and they’ve (they have).

It’s can also be a contraction of it and has when used in the present perfect tense. The apostrophe takes the place of the h and the a in has.

For example, it’s been raining is the contracted form of it has been raining.

Its

This form of its is a possessive pronoun. I, you, his, her, we, they are all pronouns but possessive pronouns are my, your, his, her, our and their.

I have a pen – it is my pen.
We have a house – it is our house.

Its is the possessive pronoun of it. It is used for animals, objects and basically anything we don't know the gender of. So you would say:

	The dog ate its food very quickly

The dog ate its food very quickly.

Look at that car – its windows are broken.
