We use the helping or modal verbs CAN, COULD & WOULD LIKE to offer, suggest, request & invite.
Modals Review – A2 Pre-Intermediate English
CAN – Use can with friends or informal settings for requests (things you want). Example sentence: Can I borrow a pen, please?
COULD – Use Could to make requests or ask for permission. Could is a more polite than can. Example sentence: Could I speak to John, please? Yes, of course.
WOULD LIKE (TO) – Use would like (to) for invitations and offers. Example sentence: Would you like to go out tonight? 2. Would you like some more cake?
Remember: We use some in questions that are offers or requests. Example: Can I have some chocolate? Do you want some bread?
