Spreu vs Weizen
wheat
'der Weizen' and 'die Spreu' both belong to the area of grain, but they stand in clear contrast to each other. Weizen refers to the useful kernels, which can be used to make flour, for example. Spreu is the empty husks and small plant parts left over when grain is processed. In the idiom 'die Spreu vom Weizen trennen' (to separate the wheat from the chaff), this contrast is used figuratively: you separate the good or important from the bad or unimportant. The words can be confused because they are often mentioned together, but they do not refer to the same thing.
