00:00Hi friends! Today we will learn more about model verbs. So let's start.

00:09In our last section, we have learned about main verbs, helping verbs, and linking verbs.

00:18Today we are going to learn about model verbs that come under the category of helping verbs.

00:26Model verbs are called so because they express modality.

00:32Some of the commonly used models are can, could, may, might, shall, should, must, and had to.

00:44Now let's learn what is this modality.

00:47Modality is the way in which something happens or is experienced.

00:53Modality in the speaker's voice gives a sense of a person's mood.

00:58For example, you must do it.

01:02Here, the speaker is in a way commanding the other person to do something, and the listener is obliged to do that task.

01:14Modality also expresses the degree to which the work is important for the listener to do.

01:22You should do it.

01:25Here, the listener, you, is given a choice by the speaker to do the work he is told to do.

01:34Modality has to do with whether something is necessary, possible, or impossible.

01:43These are the models used to express modality in English language.

02:01Now let's learn some of the characteristics of model verbs.

02:05Models never change their form.

02:08That is, you cannot add s, es, or ed after models.

06:08In past tense, we use could or couldn't to express the ability or inability to do something.

06:16For example, when I was a child, I could jump very high.

06:23Here, could expresses the ability of the speaker to jump when he was a child.

06:34Here, couldn't expresses the inability of the speaker to do something in the past.

06:42Can or could, can are also used for taking permissions and giving permissions.

10:29He wouldn't eat vegetables when he was a kid. He loves them now.

10:35Here, the speaker is providing information about someone's past activities.

10:42We can also replace the model verb would with used to.

10:48Like, he was not used to eating vegetables when he was a kid. He loves them now.

10:56When I was a child, I used to spend hours playing with my toy car.

11:03When I was young, I used to go for a walk daily.

11:07So we can use the model verb would with used to interchangeably.
