A sentence from my textbook
These people are slow to change their mind.
I guess to change their mind is an infinitive clause being a complement of slow.
But I don't quite understand the meaning , does it mean :
These people change their mind slowly?
Yes, it does mean “These people change their mind(s) slowly”.* These people are very stubborn. It takes a lot of time to get them to change their points of view.
*You might not be wrong to use the singular, but I would use minds when talking about multiple people who each have their own mind. Not your question, but I thought this should be pointed out.
