“I could barely keep a straight face.”
Your daughter made a big mistake on her science homework. It was a really funny mistake but you didn't want to make her feel bad by laughing at her, so you tried to control yourself. Later, you tell your husband this about the awkward situation.
I could barely keep a straight face.
To "keep a straight face" means to avoid laughing. You try to "keep a straight face" when something is funny but you're not supposed to laugh. This happens in situations like:
- when you're in a serious meeting but someone makes a mistake.
- when you're trying to play a trick on someone.
- when you're scolding a child who's been bad but they say something funny.
We mostly talk about not keeping a straight face or trying to keep one:
When he was talking, I tried to keep a straight face but I just couldn't.
If you "can barely" do something, it means that you are able to do it, but you almost can't do it.
For example: if you need to move a heavy piece of furniture, but it's hard for you to pick up, you can say:
There's no way I can move that! I can barely lift it.
Say that you "could barely ___" for continuous actions and situations that you had trouble with in the past:
When I first moved to Mexico, I could barely speak Spanish.
