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.

06:23Here, 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.
