Communication is the key to culture, country, people and finally a successful integration - both linguistically and culturally.
In many cases sufficient knowledge of the German language is a prerequisite for a job or academic studies. The same applies to everyday life for instance when you go shopping, have an appointment with an authority or when meeting your neighbours. Understanding and speaking German will make settling in Germany much easier.
You think the German language is difficult to learn? Maybe you are right. But patience and practice will help you handle it.
You can attend German classes at language schools, at "Volkshochschulen" (VHS, German for adult education centre) or at universities. Language schools offer more varieties concerning intensity, levels and group size. At VHS or university courses support often is less individual but they are cheaper. Online courses might yet be another alternative but you do not meet other people. Find out what is best for you and inform yourself about the possibilities in your city.
Additionally, traditional textbooks or vocabulary apps on your mobile phone might help you learning German. YouTube also offers a range of instructional videos. The overseas broadcasting Deutsche Welle further supplies you with news, podcasts or short films which are spoken very slowly especially for learners of the German language.
A so called "Sprachtandem" can also support you in your learning process. It means that you talk in German to someone whose mother tongue is German as well as in your own mother tongue. Both parties profit by the mutual support and learn. This is also a possibility to make new acquaintances and possibly form friendships. Basic knowledge of the foreign language is a prerequisite. There are several providers on the internet.
The general rule is: continual training is important. Incorporate the German language in your everyday life and do not be fearful of making mistakes. Do not let yourself be irritated by the regional dialect and ask if you have any questions. Even if south Germans occasionally find it difficult to speak "high German" they can do it!
Integration courses exceed language courses as they include cultural and socio-political orientations in your new home. They address everyday life issues newcomers might be confronted with and which might cause difficulties. They further discuss moral concepts, cultural delicacies and the way of behaving that are important to the German society. The aim is a better understanding, to settle more easily and a good togetherness in Baden-Württemberg.
Integration courses come on offer as a combination of language and orientation course. Some institutes also offer separate orientation courses. It is best to get yourself informed online about providers in close vicinity to you.
There is one reason why the slogan of our state goes "We can do anything except speak High German".
There coexist various dialects and vernaculars in Baden-Württemberg. In northern Baden-Württemberg people speak "fränkisch", in the south "badisch" and "schwäbisch". Both are Alemannic dialects and marked by small but mighty differences. Foreigners may not notice them directly, but people from the north and south will do so all the more.
