Register and grammar

Register is not only a matter of vocabulary. Many grammatical choices tell a German reader at once whether a text is formal, neutral or casual, and at C2 you are expected to control them.

Grammar as a style signal

German has one written standard, but within it there is a scale from formal (gehoben) through neutral to colloquial (umgangssprachlich). Some colloquial structures are accepted in speech everywhere but avoided in writing; others are regional and marked as non-standard. Knowing which is which lets you adapt your German to a job interview, a seminar paper or a chat.

Verb forms and register

  • Konjunktiv II: formal texts prefer the strong forms of common verbs (gäbe, käme, wüsste); speech often uses würde: Wenn es eine Lösung gäbe … versus Wenn es eine Lösung geben würde ….
  • Tense: written narration uses the Präteritum, speech the Perfekt: Er reiste nach Kochi versus Er ist nach Kochi gereist.
  • Passive and nominal style are typical of formal writing: Die Anträge werden geprüft. – nach Prüfung der Unterlagen.
  • Shortened forms such as hab, geh, 'nen, gibt's belong to speech and chats.
  • tun as an auxiliary (Ich tu grad lesen) is regional and non-standard.

Word order and small words

Spoken German often places the verb second after weil and obwohl: …, weil ich hab keine Zeit. This is common in conversation but not accepted in writing, where the verb goes to the end. Names with articles (der Ravi, die Anu) are normal in southern speech but not in formal texts. Modal particles and topic drop (Weiß ich nicht) also signal informality.

Formal German, by contrast, likes inversion and fixed phrases: Sollten Sie Fragen haben, … – Für Rückfragen stehe ich Ihnen gern zur Verfügung.

Choosing the right level

The skill at C2 is not to be as formal as possible but to be consistent. A text that mixes des Weiteren with wegen dem looks careless; a WhatsApp message full of genitives sounds ironic. Before writing, decide on the register and check the grammatical markers listed here. When you rewrite a casual text for a formal reader, go through it feature by feature: prepositions, comparisons, relative words, reported speech and tenses.

A useful exercise is to take a WhatsApp message and rewrite it as an email to a professor, then back again. You will notice how many small grammatical changes are needed.

Common mistakes

Not quiteCorrectWhy
Mein Bruder ist größer wie ich.Mein Bruder ist größer als ich.After a comparative, standard German uses als; wie is only for equality (so groß wie).
Wegen dem Stau kam ich zu spät. (formal letter)Wegen des Staus kam ich zu spät.In formal writing, wegen takes the genitive.
Das ist dem Ravi sein Fahrrad.Das ist Ravis Fahrrad.The possessive dative is regional and colloquial; use the genitive -s or von.
Wenn ich Zeit haben würde, käme ich. (formal)Wenn ich Zeit hätte, käme ich.Formal German prefers hätte to würde haben in the wenn-clause.

Practice questions

1. Formal: Wegen ___ schlechten Wetters wurde das Konzert abgesagt.

In formal German wegen takes the genitive: des schlechten Wetters.

2. Standard written German: Mein Bruder ist größer ___ ich.

Comparatives take als; wie and als wie are colloquial or regional.

3. Standard written German: Das ist ___.

The genitive is the standard way to show possession; the possessive dative is colloquial.

4. Du ___ nicht zu kommen, wenn du krank bist.

Only brauchen combines with zu + infinitive here: du brauchst nicht zu kommen.

5. Wenn es eine Lösung ___, würden wir sie finden.

An unreal condition takes the Konjunktiv II gäbe.

6. Which version is marked as colloquial?

The am-progressive is common in speech but considered colloquial in writing.

7. Formal: Während ___ Verhandlungen kam es zu Protesten.
