Hello everyone and welcome to EnglishPod.
My name is Marco.
My name is Catherine and today we're talking a little bit about going to sleep or not being able to sleep.
That's right, we are having some sleeping problems
and we're actually going to check out a couple of words related to this topic right now on Vocabulary Preview.
Vocabulary Preview.
Okay, so the first word is actually the technical word that describes being unable to sleep.
Called insomnia.
Right.
So if you have insomnia, it means that you can't fall asleep.
You can't sleep.
Okay.
So this is a pretty serious condition.
For example, if you have insomnia and you don't sleep for three or four nights,
you're not going to do very well at work, right?
Right.
Or if you're studying, you're tired at school, you can't concentrate.
So it's a very big problem.
What's that other word though?
We have insomnia, but we also have another interesting disorder.
