Present participle, modifying "pool".
Since it is a modifier, you can label it an "adjective." But we get into a very technical question.
In modern grammar terminology, not all modifiers are labelled "adjective."

AlpheccaStarsPresent participle, modifying "pool". Since it is a modifier, you can label it an "adjective."

Yes, It is modifying a noun (pool) that's why I was confused.

I must stick to modern gra

CliveIt might help to think about it this way.eg a running man a man who is runningeg a running shoe the shoe is not runningeg a swimming man a man who is swimmingeg a swimming pool the pool is not swimming

What about this:
He is reading a boring story?
boring is not an act so it must be an adjective,right?

It is one noun ("swimming") modifying another noun ("pool").

What about this:
He is reading a boring story?
boring is not an act so it must be an adjective,right?
Yes, that's what I'd call it.
