definitely (do something)

When you use "definitely", it means that you're sure. You use it to show how strongly you feel:

 I definitely want to go.

"Definitely" is often used together with "can tell":

I can definitely tell that you've lost some weight.

You use "definitely" before a verb, but you can also use it before an adjective:

I'm definitely taller than him. He's like two inches shorter than me.
