What's the difference between AM, IS and ARE?

While this may seem easy, at times it can be tricky for beginning and even intermediate ESL Learners...so it's definitely worth taking a closer look.

Let's begin with the basics of the verb TO BE:

I            AM
You       ARE
He         IS
She        IS
It            IS
We        ARE
They      ARE

Now as you can see we use AM only with "I."  We use IS with "he," "she," and "it."  Finally, we use ARE with "you," "we," and "they."

How about the negative forms of the verb TO BE?

Well, there are actually two forms of the negative in English with the verb TO BE, except in the first person singular:

I'm not 
You're not OR You aren't
He's not OR He isn't
She's not OR She isn't
It's not OR It isn't
We're not OR We aren't
They're not OR They aren't

The verb TO BE is the most important verb in any language, so it's very important to learn these conjugations. If you have trouble remembering them, write each form down 5 times in your notebook.  You can do it!
