16. Register: which German, where

Fluency at C1 means switching deliberately between registers: the same speaker uses different tenses, cases and vocabulary in a bar, a team meeting, a report and a letter to an authority.

Register Where you meet it Typical features
Spoken, informal Friends, colleagues, podcasts Perfekt for the past; dropped endings (ich hab, ich geh); gibt’s, hast du’s; tag questions (oder? ne?); wegen dem; weil followed by main-clause order in fast speech
Standard, neutral Work emails, news broadcasts, meetings Full forms, Perfekt and Präteritum mixed, some nominal style
Formal written (Bildungssprache) Newspapers, academic texts, reports, C1 exams Präteritum, Genitiv, nominal style, passive, Konjunktiv I, long participle phrases
Official (Amtsdeutsch) Letters from the Finanzamt, Bürgeramt, insurers, landlords sein + zu obligations, Funktionsverbgefüge, fixed vocabulary: Antrag, Bescheid, Frist, fristgerecht, Anlage, gemäß, hiermit, unverzüglich

Extended participle phrases

The hardest feature of formal reading is the participle phrase placed between the article and the noun: die von der Regierung gestern vorgestellten Pläne = the plans presented by the government yesterday. Read it by linking the article to the noun first (die … Pläne), then reading the middle as a compressed relative clause (die Pläne, die die Regierung gestern vorgestellt hat).

du or Sie

Sie is the default with strangers, officials, customers and in traditional workplaces. du is standard among students, in many tech companies and startups, in sports clubs and online. The older or more senior person usually offers du (Wollen wir uns duzen?). When unsure, start with Sie; being offered du is easy, taking it back is awkward.

Email conventions follow the same split:

Formality Greeting Closing
Formal Sehr geehrte Frau Schmidt, / Sehr geehrter Herr Schmidt, / Sehr geehrte Damen und Herren, Mit freundlichen Grüßen
Neutral Guten Tag Frau Schmidt, / Hallo Frau Schmidt, Viele Grüße / Beste Grüße
Informal Hallo Anna, / Liebe Anna, / Lieber Jan, Viele Grüße / Liebe Grüße / LG

After the comma in the greeting, the first word of the email is lowercase unless it is a noun or Sie.

Regional German around you

Bonn sits in the Rhineland, where everyday speech has its own colour: ich can sound like isch, das / was become dat / wat, and in Cologne dialect a starting g turns into j (jot for gut). Understand it, but model your own speech and writing on standard German (Hochdeutsch), which is what exams, news and workplaces use.

Spelling conventions that signal competence

Capitalise all nouns, including nominalised verbs and adjectives (das Lernen, etwas Neues). Capitalise Sie and Ihr when they mean formal “you”. Put a comma before every subordinate clause, relative clause and most infinitive clauses with um, ohne, statt.
