English Grammar: Giving Instructions

We use the imperative form to give orders or directions in English.

“Eat your vegetables!”
“Turn left and go straight on.”

(For more information, see our grammar page.)

We can also use the imperative form to give a warning or advice, and (if you use “please”) to make a request.

“Practise English for ten minutes a day!”
“Be careful!”
“Please take a seat.”

To make the imperative, use the infinitive of the verb without ‘to’:

Come here!”
Sit down!”

To make a negative imperative, put “do not” or “don’t” before the verb. (Don’t is more informal than “do not”.)

Don’t go!”
Do not walk on the grass.”

Giving instructions

You often see the imperative form in instruction manuals or when someone tells you how to do something.

There are often “sequencing” words to show the steps in the process. For example, “firstly”, “secondly” and “finally”.

Simple instructions to replace a light bulb

Firstly, turn off the electricity.

Secondly, remove the light bulb.

Then, screw in the new light bulb.

Finally, turn the electricity on and switch on the light.

You can also say “after that” instead of “then” and “first” / “second” instead of “firstly” and “secondly”.

Giving extra help

When you give instructions, you can help the other person with extra information and advice.
