man meaning and definition in german

Man is used in the nominative case only; for the oblique cases forms of the pronoun einer are used. For example: Man kann nicht immer tun, was einen glücklich macht. (“One cannot always do what makes one happy.”)
Since man derives from the same source as Mann ‎(“man; male”), its use is considered problematic by some feminists. They have proposed alternating man and the feminine neologism frau, or using the generic neologism mensch. This usage has gained some currency in feminist and left-wing publications, but remains rare otherwise.
