Which modal verbs make a request polite in English?
Could and would. In form they are the past tenses of can and will, but in a request they express distance rather than time — and distance is what sounds polite in English, which has no formal "you". "Could you send me the figures?" is more polite than "Can you send me the figures?". Might belongs to the same family but only fits soft suggestions ("You might want to…"), not direct requests.
- The request ladder: Can you… → Could you… → Would you mind + -ing…? Each rung adds distance.
- "Ich möchte" becomes "I'd like", not "I want" — "I want" reads as a demand in English.
- To "Would you mind…?", the answer "No, not at all" means: yes, I will happily do it.

What politeness modals actually do
German carries politeness with two main tools: the formal Sie and the Konjunktiv II. "Könnten Sie mir die Zahlen schicken?" is polite; "Kannst du mir die Zahlen schicken?" is familiar. English has no Sie, so the first tool is simply gone. That puts far more weight on the second. The modals could and would are, in form, the past tenses of can and will, but in a request they have nothing to do with time. "Could you send me the figures?" does not ask about something that was possible yesterday. The form puts distance between you and your request, and that distance is exactly what politeness sounds like in English. Grammar books often describe this as the remote form. German does the same thing with the Konjunktiv II — "Ich hätte gern", "Könnten Sie", "Würden Sie" — so the principle is already familiar to you. You just have to lean on it harder, because you cannot fall back on a Sie. Once that clicks, you stop memorising phrases and start setting the temperature of every request yourself.

The request ladder: Can → Could → Would you mind
Requests with can, could or would follow the same blueprint: modal + subject + base verb. "Can you cover the front desk?", "Could you cover the front desk?" — the verb stays cover, with no to and no ending. What changes is the rung. On the bottom rung sits can: direct, friendly, completely normal between colleagues who know each other. One rung up sits could: the default for clients, managers and anyone you do not know well. Above that comes "Would you mind…?", and here the blueprint changes, because mind is an ordinary verb, not a modal. That is why the -ing form follows: "Would you mind sending me the agenda?", not "Would you mind send". At the very top are combinations with a softener: "Could you possibly…?", "Would it be possible to…?", "I was wondering if you could…". These suit bigger favours and situations where the other person could easily say no. A please strengthens any rung but does not replace one: "Can you please…" still sits a rung below "Could you…".

Permission and offers: who is the subject?
For permission you turn the perspective around: it is not the other person who should act, it is you who wants to be allowed to. So I becomes the subject. The ladder works here too: "Can I leave early on Friday?" fits a team on first-name terms. "Could I leave early on Friday?" is the safe choice with your manager. "May I…?" sits one rung higher and reads as formal — at reception, with visitors, in very formal email. When your request directly affects the other person, use a question that acknowledges that: "Do you mind if I open the window?" or "Would it be OK if I joined the call ten minutes late?" Notice that "Would it be OK if" is often followed by a past form — distance again, not time. Offers work as the mirror image: "Shall I book the room?" offers to take a task on. "Would you like a coffee?" is the polite default for guests, and "Can I get you anything?" the relaxed version. For suggestions in a meeting, "We could…" does the job: "We could move the deadline to Monday." That is a suggestion, not a possibility in the past.

Three traps for German speakers
The first trap is the literal transfer of "Können Sie…?". Because the Sie does all the politeness work in German, "Können Sie mir helfen?" sounds perfectly correct. The literal translation "Can you help me?" does not carry that Sie with it. Between colleagues this is no problem; with clients, seniors or strangers it comes across as curt. The fix is simple: wherever you would say Sie in German, use at least could in English. The second trap is "Ich möchte". In German it is a polite form, but its nearest literal English equivalent, "I want", reads like a demand. The matching translation is "I'd like" or "I would like": "I'd like to book a meeting room for Thursday." The third trap is the answer to "Would you mind…?". The question literally asks whether something would bother you, so "No, not at all" means: it does not bother me, I will happily do it. A "Yes" would be a refusal. That is why native speakers usually answer with "No, of course not" or "Not at all", and sometimes with "Sure, no problem".

Could, would, might: politeness or literal meaning?
Could, would and might also have their literal meanings, of course, and you cannot switch those off. Could expresses past ability or a possibility: "She could speak French at five.", "It could rain later." Would builds conditionals: "We would sign if the price dropped." Might expresses an uncertain possibility: "The delivery might be late." So how do you tell whether a modal is being polite or talking about possibility? By the sentence type and the subject. A question addressed to your listener with you — "Could you…?", "Would you…?" — is in nearly every case a request. A statement with could or might — "We could…", "You might want to…" — is a suggestion that leaves the possibility open. And a past could is recognisable from its time reference: "I could not open the file yesterday." When in doubt, try the German translation: if "Könnten Sie…?" works as a request, it is politeness; if only "konnte" fits, it is past time. The possibility meanings have a lesson of their own: might-could-may (B1).

At work: choosing the right rung
The right rung depends on three things: the relationship, the size of the favour and the channel. In an email to a client you have never met, could is the minimum: "Could you confirm the delivery date?" For bigger favours you go one rung up: "Would you mind sending the signed copy back by Friday?" On the phone the effect is similar, except that your tone of voice helps; a warmly spoken "Could you…" is nearly always enough. In a meeting with your own team you can be more direct — "Can you take the minutes?" is perfectly fine there, and constant softeners would sound hesitant rather than polite. With your manager, ask for permission with could or "Would it be OK if…", not with can. And when you host a visitor, offers are your tool: "Would you like a coffee?", "Shall I show you to the meeting room?" One last point: do not overdo it. One softener per request is enough. "Could you possibly perhaps maybe…" does not sound more polite, it sounds unsure. A clear request on the right rung is the most polite form English has. How to put the same rungs to work across a whole business email is the next step: email-requests (B1).
