Whenever you go out, you first have to decide what to wear. If you're going to a rock concert or a movie with friends, you throw on jeans and t-shirt and call it a day, but if you're going to wedding or a fancy dance, you have to put on something a little more formal.

Just like you can put on formal clothes, you can also use more formal language.

Formal language is language you use in more serious or important situations. You may use formal language:

Examples of formal language include:

May I please have some more?

We examined the evidence and found nothing out of the ordinary.

I would be delighted to accompany you to the dance.

Informal language is language you use in more casual or laid back situations. You may use informal language:

Examples of informal language include:

Can I have more?

We looked at it and didn't find anything unusual.

I'd love to be your date for the dance.
