I have some basic knowledge of English grammar (this is what I think!!!). I have a question about the modal verbs can and could. Let me share what I know about these modal verbs. I have explained both the modal verbs below to make you understand what knowledge I have about them:
It can be used to show abilities, opportunities, possibilities and take permissions and requests (only in the present time).
It can be used in the past and present times. It can be used to show abilities, opportunities, possibilities (in the past as it is the past form of can), but it can also be used to take permissions and requests (in the present).
My question is can we use could in the present and future to show possibilities?
