you could have
Avresti potuto chiedere allo sbirro, se fosse stato ancora vivo.
You could have asked the cop, if he was still alive.

You could have done it yesterday.
You could have warned me.
Could you have done it?
You could have called me.
Di tante cose che avresti potuto imparare.
Of all the things you could have learned.

Sapevo che avresti potuto prenderti cura di te.
I knew you could take care of yourself.
