Danish
Danish is a North Germanic language spoken primarily in Denmark, with about 6 million native speakers. It is closely related to Swedish and Norwegian, sharing many similarities in vocabulary and grammar, and is the official language of Denmark and the Faroe Islands. Danish uses the Latin alphabet with three additional letters (æ, ø, å) and is known for its distinctive pronunciation, including the 'stød' (glottal stop).
Developers should learn Danish if they are working in Denmark, collaborating with Danish-speaking teams, or developing software for the Danish market, such as localization, customer support tools, or content platforms. It is also useful for roles in international companies with Danish offices, like Maersk or LEGO, or for academic research in Scandinavian studies or linguistics.
