>Maybe being native in the language makes a difference? Often two languages share a word, but it's much less common (or even obscure) in one of them and it's unlikely that non-natives know it. For example, "die Kartoffel" means "potato" in german, while in in polish it's "ziemniak", so they aren't similar at all. However, polish also has "kartofel" which is a word that every native speaker knows, but you won't find it in e.g. newspapers.
