“I'll warn you - It's still pretty damp.”
You and a friend are at a swimming pool. Your friend is about to get out of the pool, but he doesn't have a towel. You have one, but it's wet. You offer him the towel with this caveat.
I'll warn you - It's still pretty damp.
You use "pretty" before an adjective to show how much of that quality something has.
"Pretty ___" is somewhere between "kind of " and "really". It basically means "a little more than you expected". For example:
This soup is actually pretty good.
I think I have a pretty good shot at getting the job.
That song is pretty catchy.
Use this phrase to let people know about a problem or weakness before they find it themselves. For example, if you're going to play on a softball team but you're not a good player, you can tell the other team members:
I'll warn you - I'm not very good.
You use this phrase so that people won't get disappointed or complain.
The word "damp" means "a little wet", but it's more specialized. It's only used with a few other words. Here are the main ones:
a damp cloth
the ground is damp
"Damp" also sounds a little literary, so you're more likely to read this word in a book than to hear it in daily conversation.
Use "still" to talk about things that:
- started in the past
- are still going on
- are continuing longer than you expected or hoped
