Language of elves
The Finnish language is one of the most difficult languages in the world and John Ronald Reuel Tolkien was so inspired by it that he took it as the base of the language of elves. There are 40 synonyms for “snow” in the Finnish language, but not a single word to say “please.” However, there are a lot of funny words that other languages don’t have, for example, kalsarikännit which means “drinking in underwear.” Also, there is no future tense in the Finnish language.
