So you hear that English use the word ‘bloody’ as an expletive all the time. I just learned the German word blöde which translates as stupid. It sounds a bit like the English bloody and is similar in meaning. It’s an intensifier in German but not as intense as it is in British English. Americans don’t use the word bloody the way the Brits do.
Wikipedia tries to explain: https://en.wikipedia.org/wiki/Bloody
I think it’s time to look up the etymology of the word blood to see if their is a connection. I’ll leave that as a homework assignment as I’m too tired to continue expositing on the words. I just happened to notice the similarity.
