eigenmächtig vs berechtigt
justified / entitled
'berechtigt' and 'eigenmächtig' are clear opposites when it comes to permission. 'berechtigt' means that someone has the right or permission to do something. 'eigenmächtig' means that someone acts without the necessary permission, often against rules or without consulting others. So 'berechtigt' sounds lawful, while 'eigenmächtig' sounds problematic. The difference is especially important in work, public authorities, security, or shared decisions.
eigenmächtig
Der Mitarbeiter hat eigenmächtig die Tür geöffnet, obwohl er keine Erlaubnis hatte.
The employee opened the door without authorization, even though he did not have permission.
berechtigt
Nur die Besitzerin ist berechtigt, den Vertrag zu unterschreiben.
