00:00:01,170 --> 00:00:08,300
All right, in this grammar refresh, we'll take a look at a few ways we can use the word, let us know.

2
00:00:08,340 --> 00:00:15,970
The first way you can see here is we can use the word let you talk about permission, right.

3
00:00:16,020 --> 00:00:17,250
Or to give permission.

4
00:00:18,250 --> 00:00:24,340
And when you use that, it's going to be followed by an object and.

5
00:00:25,560 --> 00:00:28,860
An infinitive of the verb without you.

6
00:00:29,850 --> 00:00:32,880
So you're just using the main form of the verb.

7
00:00:34,310 --> 00:00:43,310
But let's look at our examples, the first one is my boss, let me take three days off in a row so we

8
00:00:43,310 --> 00:00:49,040
can see here is let me give permission followed by our object.

9
00:00:49,040 --> 00:00:54,350
Here is me and then the infinitive form without two of our verb.

10
00:00:54,570 --> 00:00:56,360
So normally it's to take.

11
00:00:56,360 --> 00:01:02,150
Right, but we take off the two and it's just take my boss.

12
00:01:02,150 --> 00:01:04,930
Let me take three days off in a row.

13
00:01:05,780 --> 00:01:06,740
Our other example.

14
00:01:07,340 --> 00:01:10,030
Why don't they let us make updates.

15
00:01:10,670 --> 00:01:13,160
Why don't they let us make updates.

16
00:01:15,150 --> 00:01:23,010
So, again, we have let me in permission or to give permission or without OK, and then our object

17
00:01:23,010 --> 00:01:25,980
is us and then our verb make.

18
00:01:26,400 --> 00:01:28,410
So why don't they let us make update's?

19
00:01:30,070 --> 00:01:32,230
Another way we can use let is.

20
00:01:33,640 --> 00:01:38,400
You use it in this phrase, let us let us.

21
00:01:39,620 --> 00:01:40,820
And if you say.

22
00:01:41,920 --> 00:01:48,790
They together fast, it led us right, kind of like the food, lettuce, the vegetable, but it's let

23
00:01:48,790 --> 00:01:49,800
us but.

24
00:01:50,720 --> 00:01:53,000
You know, when you're speaking, you don't really say.

25
00:01:54,190 --> 00:02:03,550
It very spread out, it's not let us let us take another more common way is to have it attracted into

26
00:02:03,550 --> 00:02:04,030
let's.

27
00:02:05,680 --> 00:02:06,800
You'll hear this more often.

28
00:02:06,820 --> 00:02:07,360
Let's.

29
00:02:08,390 --> 00:02:17,930
So when you have this, let us or let's it's a way that we can give a suggestion, a suggestion to do

30
00:02:17,930 --> 00:02:18,350
something.

31
00:02:19,730 --> 00:02:26,270
So in our example here, it's let's go over this report once again, and if it's not contracted, it

32
00:02:26,270 --> 00:02:29,930
would be let us go over this report once again.

33
00:02:30,680 --> 00:02:35,210
So this is kind of like a polite way to suggest that we should do this.

34
00:02:35,430 --> 00:02:38,570
OK, but let's go over this report once again.

35
00:02:40,460 --> 00:02:43,640
The next example is let's take a five minute break.

36
00:02:44,390 --> 00:02:46,070
Let us take a five minute break.

37
00:02:46,790 --> 00:02:52,910
And again, this is just a nice casual way to make some kind of gesture.

38
00:02:54,170 --> 00:02:54,560
A.

39
00:02:57,030 --> 00:02:59,130
You don't say it to a class or at work.

40
00:02:59,790 --> 00:03:02,970
Let's take a five minute break or let us take a five minute break.

41
00:03:05,720 --> 00:03:07,640
Similar we can use, let me.

42
00:03:09,060 --> 00:03:09,810
As a.

43
00:03:10,790 --> 00:03:14,270
Suggestion, but here it's.

44
00:03:16,400 --> 00:03:22,730
Referring to just you are not the group of you and the other people, so in our example here, it's

45
00:03:23,090 --> 00:03:24,320
let me call you back.

46
00:03:25,280 --> 00:03:27,590
So that's just saying kind of like.

47
00:03:28,720 --> 00:03:32,790
Or I'll call you back or let me help you with these files.
