German, Swiss German and Baseldytsch — conclusion

Conclusion

German in Basel exists in three layers that coexist without merging. Swiss Standard German is the language of laws, contracts, judgments and newspapers, a full standard variety with its own spelling and vocabulary. The Swiss German dialects are the spoken language of the whole population, carrying a prestige that sets German-speaking Switzerland apart from the classical cases of diglossia. Baseldytsch, finally, is the city dialect, a Low Alemannic variety that connects Basel with Alsace and southern Baden, finds its literary home in the Fasnacht and its classic author in Johann Peter Hebel, and preserves in its sociolect the memory of the Daig. For the financial centre, these layers have concrete consequences. The terminology of Swiss legal German requires care in cross-border mandates with Germany, while the language of proceedings determines how and where disputes are argued. The dialect, for its part, binds the local clientele to the local banks while drawing a subtle line around the international workforce.

The German-speaking world is only one of the linguistic horizons of Basel. On the other side of the border lies Alsace, which speaks French in public and, in a dwindling number of families, an Alemannic dialect closely related to Baseldytsch. The relationship between Basel and its French-speaking neighbour, which shapes labour markets, frontier work and the trinational institutions of the region, is the subject of Chapter II.

Dr Alexander Ressos, TEP

Rechtsanwalt/Attorney-at-Law

I am a Swiss attorney-at-law and also admitted as a solicitor in Hong Kong and in England & Wales, with almost 25 years of experience.

Together with my multilingual team, including Chinese, Japanese, Korean, Russian, Ukrainian and French native speakers, I advise companies and their owners from around the world on the full range of banking, corporate, commercial and tax law matters in Switzerland, including international tax planning, fiduciary services, and legal family office services including immigration & relocation or real estate investments. My practice has a particular focus on clients from growth and frontier markets in Greater China, Central Asia and the Caucasus, the rest of Asia, the Middle East, Africa and Latin America, and I equally advise clients from Europe and North America. Through an affiliated Swiss trust company, we also take care of the incorporation and ongoing administration of their companies and other structures, including accounting, tax returns and corporate secretarial services, and I serve as a professional director where required. With the support of a network of first-class cooperation partners, I also implement solutions worldwide.

My approach is to act as a trusted advisor who works directly with decision-makers, on an equal footing: I start from what you want to achieve and shape every structure, contract and tax decision around your commercial goals and how it improves your after-tax return. As “lawyers who make it happen”, my team and I stay involved until your company is set up, your structure is in place and your transaction has closed, and we remain available for any follow-on work that may be required. You benefit from bespoke solutions and personal attention, and sound, friendly and practical advice. We are not the lowest-cost provider in the market, nor do we intend to be; our aim is to deliver well-founded, proper solutions and excellent value for money.
