Estonian. With only 1.1M native speakers, Estonian isn’t a widely-spoken language. It’s part of the Uralic group of languages (that is, originating from northern Eurasia) and is considered closely related to the Finnish language but much of the vocabulary is borrowed from the German language too. Estonia is one of the most literate places in the world, with almost every Estonian speaking at least one other language (if not several). The second most common language in the country is Russian, but German and Finnish are also very common in older generations. The vast majority of younger adults speak a very good standard of English too.
