Making Requests: Can, Could, May I

Level: A1. When you need something from another person — help, a favour, or permission — English uses the modal verbs can, could and may. The grammar is easy; the skill is choosing the level of politeness that fits the moment.

The rule

A request is when you ask someone to do something, or ask for permission to do something yourself. A modal verb (can, could, may, would) is a helping verb that carries this meaning. After it you use the base verb — the plain dictionary form with no ending and no to.

There are two kinds of request, and they point in different directions:

• Asking another person to act: put the modal first, then you: “Can you help me?”, “Could you pass the salt?” You are asking the other person to do the verb.
• Asking permission for yourself: put the modal first, then I (or we): “Can I sit here?”, “May I leave early?” You are asking to be allowed to do the verb.

In both cases the pattern is the same: modal + subject + base verb + …? The modal never changes form and never takes -s, and the main verb stays bare.

The politeness scale

All of these are correct; they differ in how formal and soft they sound. Could and may are more polite than can; adding please softens any of them.

May is used almost only for permission with I or we — “May I…?”, “May we…?” — not to ask another person to act. You would not normally say “May you help me?”

How to say it

• In requests, can and could are usually unstressed and weak: “Can you…” sounds like “k’n you”, and “Could you…” often runs together as “c’juh”. The stress falls on the main verb.
• Could rhymes with good — the l is silent: say “kood”, not “kool-d”.
• A rising intonation at the end makes the request sound friendlier and more open; a flat tone can sound like an order.

Example sentences

Common mistakes

• ❌ Can you to help me? → ✅ Can you help me? No to after a modal — the base verb comes straight after the subject.
• ❌ Could you helping me? → ✅ Could you help me? Use the base verb, not the -ing form.
• ❌ May you help me? → ✅ Can/Could you help me? May is for permission with I/we, not for asking others to act.
• ❌ Can I to sit here? → ✅ Can I sit here? Again, no to before the base verb.
• ❌ Do you can help me? → ✅ Can you help me? Modals make questions by moving themselves; never add do.
• ❌ Please can you to open it? → ✅ Could you open it, please? Keep the base verb bare; please goes at the start or end.

A short conversation

A: Excuse me, could you help me for a second? B: Of course. What do you need? A: Can I borrow your charger? My phone is dead. B: Sure, here you are. A: Thank you. May I give it back after lunch? B: No problem.

Usage notes

• Saying yes and no. To accept: “Sure”, “Of course”, “Certainly” (formal). To refuse politely, give a reason: “Sorry, I can’t right now — I’m busy.” A bare “No” sounds rude.
• Please. Please can go at the start (“Please could you…”), at the end (“Could you…, please?”), or before the verb (“Could you please…?”). All are fine.
• Can for offers. “Can I help you?” and “Can I get you a drink?” use the request form to offer, not to ask for yourself.
• Would you mind. A very polite alternative uses the -ing form: “Would you mind opening the window?” Note this one does take -ing, because mind is the main verb here, not a modal.

Compared with…

• Can for ability uses the very same word but means is able to, not a request: “I can swim” describes a skill, while “Can you swim?” can be either a question about ability or, in context, a request. See Can and Can’t for Ability.
• Could for the past and politeness is the softer partner of can. As a past form it means was able to (“When I was young I could run fast”); as a request it is simply more polite than can. The full picture is in Could for Polite Requests and the Past.
