German
German may appear a little more familiar to English speakers than other languages, however, it's still not simple. They belong to the same language family, which explains why. It is also spoken in Austria and Switzerland in addition to Germany. For people who want rigid grammar rules, German is a great option.
Prior to English's replacement after World War I, German was regarded as "the language of science". However, German continues to have a rich tradition of academic and scientific literature, making it a great language to study if those subjects are among your interests. The majority of the European Union's population speaks German as a first language, providing countless travel options across the continent! German is an important language for business since it is the third-largest exporter in the world and has the fourth-largest GDP.
