Hey kids, it's Luis. I'm going to explain you the difference between must and mustn't, okay?

2
00:00:06,969 --> 00:00:11,410
Must is a modal verb and it works the same as can, okay?

3
00:00:11,570 --> 00:00:16,170
But we use must when we talk about obligations, okay?

4
00:00:16,449 --> 00:00:20,030
Things that you must do are obligations.

5
00:00:20,410 --> 00:00:25,670
For example, you must be quiet when you are in class.

6
00:00:25,670 --> 00:00:34,670
you must wear your mask when you go outside okay and mustn't means the opposite okay

7
00:00:34,670 --> 00:00:42,950
it's not an obligation you mustn't shout okay you mustn't whisper you mustn't run around

8
00:00:42,950 --> 00:00:46,869
okay it's the opposite so that's all hope that you have a nice day
