Du vs. Sie: When to Use Each in German

English used to have a polite “you” too — thou was the casual one — but it died out centuries ago, leaving us with a single, socially weightless you. German never made that trade. Every time you address someone, you have to pick a social temperature: warm and familiar, or respectful and distant. There’s no neutral middle word to hide behind, and that’s exactly the moment most learners freeze.

Here’s the good news: this isn’t really a grammar problem, it’s a who-am-I-talking-to problem. Get the situation right and the words follow. Below is a decision card you can run through in the half-second before you open your mouth in a café, a job interview, or a conversation with your landlord.

Du, Sie, and ihr at a glance

German actually gives you three flavors of “you,” and they sort by intimacy and number.

German	English	When
du	you (informal)	one friend, child, family, pet
ihr	you all (informal)	several people you'd each call du
Sie	you (formal)	strangers, elders, work — singular AND plural

The single most important spelling rule in German address: Sie is always capitalized when it means formal “you.” Lowercase sie means “she” or “they,” and they share the exact same verb form. In writing, the capital letter is the only thing telling your reader you mean them, not her. In speech, context carries it — but get the capital wrong in an email and you can accidentally write “did she see that?” when you meant “did you see that?”

Two verbs name the act of choosing itself, and they’re worth knowing: duzen (to address someone with du) and siezen (to address someone with Sie). Germans really do say things like „Duzen wir uns?” to negotiate which one you’re on.

The grammar you can’t skip: Sie takes a plural verb

This is the part English speakers consistently trip over. Sie uses the plural verb form — the same endings as sie meaning “they” — even when you’re talking to one person. du has its own endings, and ihr has its own.

Verb	du (informal)	ihr (plural)	Sie (formal)
sein (to be)	du bist	ihr seid	Sie sind
haben (to have)	du hast	ihr habt	Sie haben
gehen (to go)	du gehst	ihr geht	Sie gehen
können (can)	du kannst	ihr könnt	Sie können

Same question, three temperatures: Wohin gehst du? to a friend, „Wohin geht ihr?” to a group, and „Wohin gehen Sie?” to your boss.

The other quiet killer is the pronoun’s case. The nominative is easy — everyone gets Sie right as the subject. It’s the object forms that bite. Formal “you” becomes Ihnen in the dative and Sie in the accusative, while the possessive is Ihr-. The informal set runs dich / dir / dein-.

German	English
Wie geht es Ihnen?	How are you? (formal, dative)
Wie geht es dir?	How are you? (informal, dative)
Darf ich Sie etwas fragen?	May I ask you something? (formal, accusative)
Ist das Ihre Tasche?	Is this your bag? (formal, possessive)

The classic slip is saying „Wie geht es Sie?” — you reached for the subject form when the verb wanted the dative Ihnen. If the case system itself feels shaky, the German cases guide untangles exactly when each pronoun changes shape.

The situational cheat-sheet: which one, where

The default rule of thumb: when in doubt, use Sie. Being too formal is a small stumble that earns a friendly correction; being too informal can land as disrespect. Here’s the room-by-room version.

Situation	Use	Notes
Stranger on the street	Sie	directions, the time, any quick exchange
Café or shop staff	Sie	customers always get Sie
Trendy bar / club / festival	du	youth-dominated, peers duzen freely
Traditional office	Sie	until the du is offered, usually by the senior person
Startup / tech / agency	du	often blanket du company-wide
Older people you don't know	Sie	a big age gap means Sie upward
Children and young teens	du	no offer needed; ihr for a group of kids
Police and officials	Sie	always — see the legal note below

Three dials decide it: age, power, and intimacy. Younger, lower-rank, or closer to you nudges toward du; older, higher-rank, or unknown pushes toward Sie. And remember that setting overrides identity — the same neighbor is Sie to you across the bank counter and du at the climbing gym. A useful opener for any first contact is a polite Entschuldigung, which buys you a beat to read the room before you commit.

Who offers the du — and how to switch

Moving from Sie to du is a small social event, not a casual drift. It’s normally offered out loud, and there’s etiquette about who gets to offer it. Privately, the older person extends the du to the younger. At work, the more senior person offers it down the ranks — a boss may offer du to a report, but a report shouldn’t jump the gun. When age and rank disagree, defer and let the other person move first.

German	English
Wollen wir uns duzen?	Shall we use du with each other?
Sie können gerne du zu mir sagen.	You're welcome to say du to me.
Ich würde gerne beim Sie bleiben.	I'd prefer to stay with Sie.

To accept, a warm gerne (“gladly”) and your first name does the job. To decline without offense, you reach for bleiben: „Bleiben wir lieber beim Sie.” And once you’re on du with someone, don’t quietly revert to Sie — switching back is read as a deliberate cooling of the relationship, not a return to politeness.

The in-between forms

Real workplaces blur the line with two named hybrids. The Hamburger Sie pairs a first name with formal Sie — „Werner, reichen Sie mir den Vertrag?” — a friendly-but-respectful northern compromise. The Münchner Du does the reverse, a surname with informal du, and can read as over-familiar if you misjudge it. You’ll mostly hear these rather than need to produce them; recognizing them just stops the apparent rule-breaking from confusing you.

Germany is shifting toward du

The default is genuinely moving. IKEA Germany has used company-wide du for decades; advertising leans almost entirely on du to sound close and youthful; tech and creative companies often mandate blanket du from the interview onward; and online — social media, apps, forums — du is simply the norm. Under-35s duzen far more readily than their grandparents did.

That said, the safe play when you’re the newcomer is still to open with Sie and mirror what comes back. Mirroring beats guessing every time. If you want the broader politeness picture — greetings, please-and-thank-you, and how register colors them — the German false friends list is a good companion for sidestepping the words that feel right but land wrong.

You won’t get every call perfect at first, and that’s completely fine — Germans themselves admit the boundary is fuzzy. Lead with Sie, watch for the offer, and let the room teach you. Next time you’re ordering a coffee, try the formal opener out loud and feel how natural it gets.
