In Europe, as the domestic market is generally quite restricted, international trade is a norm. But there is no predominant language in Europe (with German spoken in Germany, Austria, Switzerland, Liechtenstein, Luxembourg, and Belgium; French in France, Belgium, Luxembourg, and Switzerland; and English in the United Kingdom, Ireland, and Malta). Most of the time, English is used as a communication language, but in multilingual countries such as Belgium (Dutch, French, and German), Switzerland (German, French, Italian and Romansh), Luxembourg (Luxembourgish, French and German) or Spain (Spanish, Catalan, Basque and Galician), it is common to see employees mastering two or even three of those languages. Some languages such as Danish, Swedish and Norwegian; Serbian, Croatian and Slovenian or Czech and Slovakian are so close to each other that it is generally more common when meeting to use their mother tongue rather than English. During Czechoslovakian times, Czech and Slovakian used to be the same language, but two different dialects as well as during Yugoslavian times Croatian, Serbian, Bosnian and Montenegrin used to be one language with more dialects. After the Yugoslavian breakup, each state created its official language from their dialect. Name of the original language used to be called Serbo-Croatian. In spoken form, there is almost no difference between Serbian and Croatian. In written form, Serbs use Cyrillic and Croatian Latin.
