Unit 4: Language Functions

A language function explains why someone says something. For example, if you are teaching a class you'll have to give instructions. "Giving Instructions" is the language function. Language functions then require certain grammar. To use our example, giving instructions requires the use of the imperative. For example:

• Open your book
• Insert the DVD into the drive
• Purchase your ticket online

There is a wide range of language functions. Here are examples of guessing, expressing wishes and persuading—all language functions. 

Guessing

• He might be busy today.
• She must be at work if she's not at home.
• Maybe she's got a new boyfriend!

Expressing Wishes

• I wish I had five million dollars!
• If I could choose, I'd buy the blue car. 
• I'd like to have a steak, please

Persuading 

• I think you'll find our product is the best you can buy.
• Come on, let's go have some fun! What can it hurt?
• If you give me a moment, I can explain why we should do this deal.

Thinking about which language function you'd like to use helps you learn phrases used to accomplish these tasks. For example, if you want to make a suggestion you'll use these phrases:

• How about ...
• Let's ...
• Why don't we ...
• I'd suggest we ...
