Does anyone knows how to identify between have pp / have been pp? I have confused until now. For example, "i have known" , "i have been known"
Which one is wrong? And why?
In your example, I have known would mean that it was I doing the knowing, whereas I have been known would mean that someone else is doing the knowing about me. So, the difference is actually active and passive voice.
Have means to possess, own, or hold something that can be a quality, characteristic, or feature.
We use the Present Perfect Continuous have been
to show that something started in the past and has continued up until now.
