In English, "can" and "could" are modal verbs that express various concepts.
"Can" refers to someone's ability to do something right now, like speaking a language. It also suggests that something is possible, such as making a mistake in a game.
When we give permission or ask someone to do something informally, we use "can." For instance, we might offer a friend our car or ask for help.
"Could" is the past tense of "can" used to discuss past abilities or possibilities. It's also a polite way to ask for permission or make a request and to give suggestions or offer help conditionally.
