Duzen or Siezen: the du/Sie decision, explained

The safe default for an adult stranger in Germany is Sie, and it stays Sie until the other person offers du. That single rule will carry you through 90 percent of situations. The remaining 10 percent - the startup office where everyone duzt, the climbing gym, the Bavarian village pub, the neighbour who has been Herr Weber for six years and suddenly says "sag doch Thomas" - is where learners get uncomfortable, because the decision is social, not grammatical.

And that is the real point: getting Sie wrong is not like getting a dative ending wrong. Nobody minds mit dem Auto becoming mit das Auto. But siezing a colleague who explicitly offered you du reads as a cold shoulder, and duzing a 60-year-old official reads as either contempt or cluelessness. The grammar takes an afternoon. The calibration takes a year of paying attention.

The default in each setting

Here is what to assume when you walk in cold. Assume, then adjust to whatever the other person actually does.

The pattern behind the table: institutions siezen, communities duzen. Wherever people are there voluntarily and share an interest - sport, church groups, hobbies, hacker meetups, political parties, the CCC - du is the entry ticket. Wherever money, authority or paperwork changes hands, Sie.

Who offers the du, and how it is done

The offer comes from the person with more standing in the room: older to younger, boss to employee, host to guest, the person who was there first. As a newcomer and usually the younger party, your job is to wait. Accepting is automatic - you say yes.

The standard formulas are worth learning as fixed chunks rather than words:

• Wollen wir uns nicht duzen? - the classic offer.
• Sagen wir doch du. - slightly more direct.
• Ich bin der Thomas. - the Bavarian/Austrian version; the definite article plus first name is the offer.
• Gerne, ich bin Anna. - the standard acceptance, and you give your first name back.

Once du is given, it is permanent and it applies in both directions. There is no going back to Sie without making a statement; retreating to Sie mid-relationship is how German novels signal that a friendship has ended. Also note that the offer is person-specific: being on du terms with Anna in accounting does not extend to her boss.

Two hybrids exist and confuse learners badly. The Hamburger Sie is first name plus Sie ("Anna, koennen Sie kurz..."), common in agencies and media as a friendly-but-not-intimate middle ground. The Muenchner Du is du plus surname, mostly in Bavarian traditional and political circles. Neither is a mistake when a German does it. Do not initiate either.

The grammar, in ninety seconds

The forms are easier than the etiquette. Sie is simply the third person plural conjugation with a capital S, everywhere, always.

Three traps. First, there is no polite plural separate from polite singular - Sie covers one person or twenty. Second, ihr is the plural of du, and forgetting it produces the classic learner error of siezing a whole group of friends. Third, the capital letter matters in writing: sie kommen (they come), Sie kommen (you come). In emails, Du and Dein are also often capitalised as a courtesy, though the current Duden rule makes it optional.

The pronoun tables and imperative forms live in the grammar library; the fixed politeness formulas - Wollen wir uns duzen, Wie darf ich Sie ansprechen - sit better in collocations, because you want them out of your mouth whole, not assembled on the spot.

Regional and generational drift

The map is moving, unevenly. Broad tendencies, all with exceptions:

• North vs south. Northern cities are more consistently Sie with strangers; rural Bavaria, Austria and Swabian villages duzen locals in the pub and siezen the same people at the Rathaus.
• Switzerland. Swiss German duzt considerably more readily in workplaces, but written Hochdeutsch stays formal. Austrians keep Sie plus title (Herr Doktor, Frau Magister) alive far longer than Germans do.
• Age. Under-30s duzen each other across almost every context outside customer service. If you are 25 and someone your age siezt you, they are being professional, not distant.
• Companies. Some firms have a written du policy from CEO down - Otto, many DAX tech units, most agencies. Others remain Sie between people who have shared an office wall since 2013. Neither is unusual, and you find out on day one by listening in the kitchen, not by asking HR.

If work German is your actual problem, the workplace-specific conventions - email openings, meeting register, the moment your manager offers du - are covered in German at work, and the broader social logic in our culture notes.

What Germans do when they are unsure

This is the useful part, because native speakers face the same ambiguity and have built an entire evasive toolkit for it. Steal it.

• Avoid the pronoun. "Danke!", "Alles klar?", "Geht das?", "Kein Problem." None of these commits you.
• Use `man`. "Wie macht man das hier?" instead of "Wie machst du das?"
• Use the infinitive imperative. Signs and instructions do it constantly: "Bitte anschnallen", "Kurz warten". It sounds natural spoken too.
• Use `wir`. "Sollen wir das morgen machen?" dodges the choice entirely.
• Ask outright. "Duzen wir uns hier eigentlich?" is a completely normal question in a new workplace, and asking it marks you as socially aware, not as a foreigner.
• Mirror. Whatever the other person's first sentence uses, use that. In email, mirror the greeting: Sehr geehrte Frau Weber gets Sie, Hallo Anna gets du.

Recovering when you get it wrong

You will slip. The recovery is short, light and immediate - the worst response is a long apology that makes everyone examine the moment.

• You duzed someone who expects Sie. "Entschuldigung, ich bin ins Du gerutscht." A smile, move on. If you are visibly a learner, most people will not even register it.
• You siezed someone after they offered du. "Sorry, ich muss mich noch umgewoehnen." This one is worth catching, because repeated Sie after an offer looks like a refusal.
• You offered du and got a polite deflection. Rare, and it usually sounds like "Ach, lassen wir es erstmal beim Sie." Accept it in one beat and never mention it again.
• You forgot whether you are on du with someone. Use the avoidance kit above for one conversation and check with a colleague afterwards.

One honest limit: no app, including this one, will calibrate your social instinct. Drills give you the forms instantly and automatically, which is genuinely necessary - you cannot read a room while conjugating. But the reading itself comes from hours with real people. If that is your bottleneck, an hour a week with a tutor on italki at roughly 15 to 25 EUR, or a Stammtisch that costs nothing, will do more for your du/Sie sense than any amount of review. Use both.

Make the forms automatic, then forget them

The goal is that Ihnen, euch and setzen Sie sich arrive without thought, so your attention is free for the social read. That is exactly what spaced repetition is for: our decks drill the pronoun and imperative sets with native audio and full sentences, so you hear the register rather than memorising a table. Start with the free tier and see whether the forms stick before you look at pricing - and add the politeness formulas from collocations as whole phrases, because Wollen wir uns nicht duzen? is not a sentence you want to build from parts in the moment it matters.
