>>213128688 (OP)Ukrainians, Belarussians and Lithuanians have exactly the same myth, they believe their native languages were invented by innocent elves while one day ugly brute Russians/Poles came and forced them to learn disgusting swearwords.
In reality it's because "ugly" cursewords are highly tabooized in rural societies so any society which is mostly composed of peasants, without a strong working class/intelligentsia, will usually use only "weak" curses. I'm pretty sure Slovenes have a great number of typical rural swearwords related to animals, comparing people to dogs, cows, pigs etc. But swearwords about intimate parts of the body or sex overall are highly tabooized in the countryside mentality so they only started using them during rapid urbanization and industrialization in the communist era, which coincidentally, in case of Yugoslavia, was strongly connected to imposition of Serbo-Croatian language onto all Yugoslav nation (in the USSR the same happened with Russian language).
