My friend asked me a question today:
Woher kommen deine Eltern?
and I wanted to answer
My parents come from Afghanistan.
I know that the nationality in German for "Afghan" is afghanisch with die Afghanin and der Afghane for the respective individuals.
I failed to find any source for when the people in concern are plural.
What happens in that instance? Do we add the plural ending to "afghanisch" i.e. afghanische or what happens?
I thought it would be
Meine Eltern sind afghanische
but I'm not sure.
EDIT my other thought was
Meine Eltern sind Afghanen.
but again I'm not too sure.
