So, first of all, the basics.

Here are a couple of examples of the command form from The Avengers.

-Dread it.

-Run from it.

All you need to do is have the infinitive form of the verb and drop the "to" in front of it.

For example, the verb "to like" becomes "like."

You also have to make sure that there's no subject in front of the verb.

Usually you'd say, "I go," "she sings," "my mom works."

There's always a subject, right?

With the imperative, all you need is the verb "without to."

You could add an exclamation point at the end because often when we speak commands, we shout them.

-Hulk, stop breaking everything!

It doesn't matter how many people you're commanding, that's all you gotta do.

If you want to follow along while we check out a couple of different forms of the command form, I'm gonna leave a link in the description box or a free trial of FluentU, so check it out.

If you want to form the negative command form, that is "to tell someone not to do something," there's an extra little step you've gotta do.

All you need to do is add "do not" in front of that verb stem, that is the infinitive verb without the "to" in front of it.

-Please, don't do this.

-We have time. We can work it out.

If you want to include yourself in the command, so it's more of a suggestion for a group instead of a direct order, you can add "let's" in front of the verb.

-Put on the suit. Let's go a few rounds.

You can even give warnings or advice with the command form, but it's all dependent on how your voice sounds.

If I say, "look out," does that sound like a command?

Nope!

What if I said something more like this?

-Look out! Look out! Look out! Move! Move! Move!

Did you notice how the tone of the second word is higher and the volume of the second word is higher?

Look out!

That's how you signal a warning.

You can also use the command form to make requests, but make sure you add "please" in front of the command and that you speak in a very nice, calm tone of voice.

-Sir, please put down the spear.

Now, it's your turn.

Think of a verb and turn it into a command.

Then turn it into a negative command.

Make sure to write in the comments what you came up with, so I can take a look.

Let's watch a clip from the "Avengers: Infinity War" trailer.

There are three more command forms that you're going to hear.

See if you can pick them out.

- Evacuate the city.

-Engage our defenses.

-And get this man a shield.

Exactly, they were from King T'Challa, and how do we know that they were command forms?

For one, King T'Challa doesn't use a subject, and he only uses the verb stem, that is the infinitive form of a verb without the "to."

Let's check our answer.

FluentU tells us that we chose correctly.

We picked out the imperative.

Here's a couple more tests.

Can you pick out the imperative forms?

- You got a suit?

- Yeah.

- Then suit up.

- Guys...

- Call it, captain.

- All right, listen up.
