Verbs can also be fiddly because sometimes verbs aren’t doing anything. There are three different types of verbs.
These are the verbs we think of when we think of verbs. These are the “doing something” verbs. When they are in their unconjugated form, they are what we call infinitives. Infinitives begin with the word to and look like this:
to run
to sit
to fight
to love
“to sleep, perchance to dream . . .”1
When we pair verbs with a subject, we conjugate them. To sit becomes she sits. If it happened yesterday, sit becomes sat.
Linking verbs are what we call “existence verbs,” and they come in two categories.
I am excited.
He is my brother.
You look great.
He sounded tired.
That feels soft.
In none of these is the subject doing the action of looking, sounding, or feeling. Make sense?

The last type of verb has to be paired with either an action verb or a linking verb, and helps to create the more complicated tenses, progressive and perfect. In these tenses, the to be verbs can also be helping verbs, if they are paired with an action or linking verb. Take the following, for instance:
I was thinking about that.
I am thinking about that.
The action verb in that sentence is thinking, but the use of am or was changes the tense.
They also communicate meanings such as expectation, permission, and obligation, among others. These are the “shoulda-woulda-coulda” verbs.
If someone says, “I went to the movies,” it means just that. But if someone says, “I should have gone to the movies,” the action verb is gone, but then what are the words should and have? They are helping verbs, used to change the meaning of gone. Now the sentence implies that I didn’t go to the movies and that I regret it. Here is additional information on helping verbs.
Now that you have a handle on nouns and verbs, let’s practice.
