which or what

When do we use which and what?

Word	Explanation	Example
which	You have a limited choice of things.	Which lemonade do you like – green or pink?
what	ou have an unlimited choice of things.	What lemonade do you like?

With nouns that refer to people, sometimes which is used – even if there is an unlimited choice.

It is often possible to use what or which, like in the following example.

• What is the largest country in the world?
• Which is the largest country in the world?

BUT – if you choose sth from a group of things, use which.

• Here are three apples. Which would you like?
