Okay. Let's take a look at the note here. This idiom is often used as someone

going to bed. So while they're going to bed. This is when you may say that to

them. It basically means to sleep well or warm

and safe. That's that idea is kind of suggested as

well. It tends to be used more with children. So we often say to children ,

you know, sleep tight for you know, little kids. All right. Let's continue. One belief of

the origin goes all the way back to when mattresses were supported by ropes. They

used to pull them and tie them with ropes. If one slept tight, it meant that the

ropes were pulled tight. This allowed for a more comfortable bed. Okay. Well that's

one theory that's one idea. It sounds like it could be logical, but then we have

opposing points of view here. Others claim that this belief is incorrect or

not correct, and that tight used to mean soundly or properly. So it had another

meaning at one time to mean soundly or properly. Therefore sleeping tight meant

to sleep soundly. You know, in a very deep sleep. So not waking up easily. So

that sort of is a better sleep. All right. And let's look at a couple of

examples here. Example one. It has both an a/b part. A says I'm exhausted. I think I

will turn in now. Turn in means you're going to go to bed. If you're going to say that

you're gonna turn in for the night, it means., yeah you're going to bed. You're

going to go lie down in bed, And B says, okay, sleep tight, Don't let the bedbugs bite.

Yeah we hear this one a lot. Sometimes. we actually follow 'sleep tight' with don't

let the bedbugs bite. Even though , to be honest with you in the

West. There's really not many bed bugs. We do know that bed bugs do exist,

and I have seen them in a number of countries where there really are bed

bugs. I don't know maybe in the US it's

possible maybe has somebody that works on farm. They'd be more likely to get

them, but I remember even as a kid thinking bedbugs. Do they really

exist ? Why did they say bedbugs, but I did find out later on that I have seen

bedbugs. I know what they look like. Yeah. So anyway but sometimes you hear that

put together. Sleep tight , don't let the bedbugs bite.

So hopefully somebody's not going to bed knowing that there is bedbugs there.

Hopefully they try to get rid of them somehow.

All right. Anyway, number two here is " Good night. Sleep

tight. See you in the morning. ' That's the way we would usually say it. So just

again, just as they are going to bed. That's when you say sleep tight.

Anyway, I hope you got it . I hope it is clear. Thank you for your time. Bye-bye.
