What makes a good English to Swiss German translation

It‘s a dialect, not a language

Unlike translating into standard German, Swiss German has no single written form. A good translation means choosing the right regional variety – and writing it the way it‘s actually spoken.

English idioms don‘t translate directly

English phrasing transferred word-for-word into Swiss German immediately sounds unnatural. Native speakers notice. The goal is to find the equivalent expression – not the equivalent word.

Register matters

How informal is informal? Swiss German has layers – from casual spoken dialect to semi-formal written dialect. Marketing copy, chatbot flows and social captions each need a different approach.

Credibility is everything

Text that sounds “almost” like Swiss German stands out – and undermines trust more than standard German would. Authentic dialect requires native knowledge, not approximation.

From Swiss market entry to digital customer experience – here are the most common use cases for this language pair.

SWISS MARKET CAMPAIGNS

Social ads, OOH copy, campaign texts

Swiss German isn’t German. It’s a dialect – and there is more than one.

Available

Zurich German

The most widely spoken Swiss German dialect. Distinctive for its sharp, guttural “ch” sound and vocabulary that's immediately recognisable – such as “Tschau” as a farewell and “Velo” instead of bicycle. Sounds like Zurich.

Available

Bernese German

The dialect of the Swiss capital – warm, melodic, unmistakable. A charming detail: “Dir” replaces the standard “Ihr” for the plural you.

Insight

More written than you’d think

Swiss German isn’t just for spoken content. In chats, on social media and in informal business contexts, the dialect is being used more and more often in writing – with its own conventions that differ clearly from standard German, and even more so from English.
