I. Theory
In German, as well as many other European languages, we find more than one verb used to convey the state of knowing. In German, the distinction is made between knowing a
fact and
knowing about something or being familiar with it.
II. Wissen
In most situations, wissen is used mainly to convey “to know”, and as a noun,
das Wissen actually translates directly to “knowledge.” This verb is used anytime the speaker is referring to knowing
facts. For this reason, it can either start a subordinate clause or take a direct object.
