So 'Kleider' means both clothes in general, and plural of dress?
No, Kleider (dresses) is the plural of das Kleid. Die Kleidung means clothes in general.
Is "die Kleidung" interchangeable with "die Kleider" or are there differences?
One is clothing, the other is dresses.
Die Mädel tragen Kleider
is it wrong?
my thought was to try*
die Mädels tragen Kleider
I think "Mädel" is regional, esp. Austria, and Duo does not take account of specifically regional expressions.
Is Die Madchen tragen die Kleider THAT different from the translation? If so, how? Thanks!
