Tatwaffe vs Waffe
weapon
'Waffe' and 'Tatwaffe' both refer to an object that can be dangerous or used in violence. 'Waffe' is the general term: it can refer to combat, hunting, threats, or even figuratively to a means used in an argument. 'Tatwaffe' is much more specific and belongs to the area of police, court, and crime. It means the object with which a crime was committed. Learners may confuse the words because a 'Tatwaffe' is often also a 'Waffe'. But not every 'Waffe' is a 'Tatwaffe'. 'Tatwaffe' is used only when talking about a specific act or crime.
Tatwaffe
Die Polizei sucht noch die Tatwaffe, weil sie für den Prozess wichtig ist.
The police are still looking for the weapon used in the crime because it is important for the trial.
Waffe
Der Polizist nahm dem Mann die Waffe ab.
The police officer took the weapon away from the man.
