I'm planing on backpacking across Europe next year and I hate being the dipshit who only speaks one langue. I already have a small amount of german and spanish so those are the only two I'm interested in. I get the impression that outside of Spain spanish isn't spoken much but I do plan on traveling south america at some point too so spanish is going to be needed eventually.
In (rural parts of) countries like Czechia and Poland there’s a lot of people that don’t speak English but do understand German.
