Multilingualism is a principle that is upheld within the EU and aims to protect the rich linguistic diversity within its boundaries. It also promotes the learning of other languages in Europe.
Although no expat is expected to be fluent in the local language of their European destination, it always helps to understand the basics. Whether that means taking a short course before you move or registering for tuition on your arrival, you will likely feel the benefits of understanding simple written phrases and greeting the locals in their native tongue.
