How should one translate 'die See'?
There seems to be some inconsistency in the way the DuoLingo lessons respond to the translation of 'die See'. When is a 'See' a 'lake' and when is it a 'sea', when there is practically no context?
Translating "die See" into "ocean" is not quite right, although there may be situations where it is okay. The simplest way of keeping both meanings apart is to think of "die Nordsee, die Ostsee" (real seas), der Bodensee is a vast LAKE between Germany, Austria and Switzerland. Besides "die See" the Germans have the word "das Meer" which means sea also: "das Mittelmeer, das schwarze Meer".
