My native language is a romance language, so I can make an educated guess in one of those most of the time and be 80% accurate, more or less. Same with germanic languages, but that’s because I know English and studied German in college. But from there to confidently translate stuff or be certain I’m not falling to the traps u mentioned, there’s a really long way.

Then, trying that with the linguistic lacunae that are languages like Basque, Balkan languages, Finnish, Russian, Polish, and so on, it’s impossible.
