全然変わらないよ。

thanks a lot!

Well, there IS a little difference, though it's very small. For example, I'd give you an "Einführung" in a new topic, or your new job. As for "Einleitung", e.g. a text can have an "Einleitung".

Hi Ryota, The "Duden" (German-German dictionary which you probably know) lists "Einleitung" and "Einfuehrung" as synonyms: http://www.duden.de/rechtschreibung/Einleitung Both can be translated as "introduction". Anja
