I need some author's guidance from people with extensive experience in other languages. I'm looking for an understanding of profanity/vulgarity in French, German and Russian, most especially if you can comment on profanity and vulgarity that would have been used 100 years ago (during the Great War.)
Thus far I've done a certain amount of reading around about this in regards to French, and my initial impression is that French does not have nearly as much variety of profanity or vulgarity as English. I came across "merde" and "zut", neither of which is apparently all that bad. Is there anything else out there? That seems pretty tame compared to English in which the world wars brought "fuck" in its many manifestations into general usage. (I gather the Australians are often blamed for this, but who is to say.)
What is out there for German and Russian? Am I simply spoiled by English? Do we have an unusual range of things to call people and exclaim?
