 Essential Question

How do different kinds of verbs show past tense?


Grammar in the World

Take a look at these two cartoons.  What is wrong with how they are talking about the past?

While adding an -ed to the end of a verb usually works to make it past tense, there are some verbs where it just sounds.... well, weird to do that.  That is because English verbs haven't always used that one marker to show the simple past tense.  Today, we refer to those older, non-standard forms as irregular, and there are many of them. How would you change the irregular past tense verb in each cartoon to make what the characters are saying sound right?

answer

 

In this lesson, we will review regular verbs in the simple past, and then take a look at verbs that don't follow the simple formula of adding -ed to the end.  But first, let's see what you already know.

What Do I Know?

What do you already know about verbs that don't follow the same rules as regular verbs? Use this interactive exercise to find out. 

Decide which type of verb is in bold – either regular or irregular. When you think you know, click the verb to see if you are correct.

  1. The Space Needle opened to the public in 1962. 
  2. This landmark began as a sketch of a flying saucer. 
  3. They built it in 400 days.

Learn About Regular and Irregular Past Tense Verbs

Regular Verbs

For simple past tense, we form regular verbs by adding -d or -ed to the base form of the verb. 

There are a lot of rules. Don’t worry if they don’t all make sense now or if you can’t memorize them. If you remember that regular verbs end in -d or -ed, you understand the most important part and can work on spelling the rest of the verb correctly as you learn more.

To explore some of the spelling rules for adding -d and -ed, click on the tabs below.

Regular Verbs: -ed

Add -ed to most verbs:

Base Form of Verb

Irregular Verbs

What about all those verbs that do not end in -d or -ed? Those are called irregular verbs, and they follow their own rules. Even though they are irregular, they actually are more common than regular verbs. Because they are so common, we remember how to say them (even though they don't follow the rules).  The English language is filled with irregular verbs.

We don’t say “I amed tired,” or “I haved a snack after school.” Instead, we use irregular verbs to replace “am” and “have.” So, the first set of irregular verbs you will want to memorize are forms of to be, to do, and to have. (These verb types are also known as auxiliary or helping verbs.)  


To Be

To Have

To Do

Simple Present

I am

We are

You are
She/He is

They are

I have

We have

You have
She/He has

They have

I do

We do

You do

She/He does

They do

Simple Past

I was
We were
You were
She/He was
They were

I had

We had

You had
She/He had

They had

I did

We did

You did

She/He did

They did


Note-- though irregular, the past tenses of "have" and "do" still end with the "d" sound and letter.  

Other common irregular verbs are to say, to see, to take, to go, and to get.

 

We say, “What a beautiful sunrise!”
We said, “What a beautiful sunrise!”

 

I see the Seattle skyline.
I saw the Seattle skyline.

 

They take a long walk after lunch each day.
They took a long walk after lunch today.

 

He goes to Seattle every summer.
He went to Seattle last summer.

 

I get excited when the elevator rises.
I got excited when the elevator rose. 

 

You will also know that can and will are irregular verbs. 

 

I can see the Space Needle from my hotel room. 

I could see the Space Needle from my hotel room.

 

She will be one of a million guests at the landmark this year.

She would be one of a million guests if she visited the landmark this year.  

 

There are many more irregular verbs. You will recognize them more as you speak, read, and write.

keep

hold

Irregular verbs are common but tricky. They follow lots of different patterns without set rules, so we learn them only because we use them so often. Practice using irregular verbs in the last activity.
