Not 'easier' than accidentally confusing 'murder' and 'murderer' in
English when coming from a German background: The German 'Moerder' is
the same as the English 'murderer' and the German translation for
'murder' would be 'Mord' while 'Moerderer' doesn't make any sense.
Astoundingly difficult stuff like that is routinely expected from fifth
or sixth form puplis and draconically punished when done wrong.
