beteuern vs behaupten
to claim / assert
'behaupten' and 'beteuern' are both used when someone says that something is true. The difference lies in the tone and the situation. 'behaupten' often sounds neutral or slightly doubtful: someone says something, but there may be no proof. 'beteuern' is stronger. It means that someone insists on something very emphatically, often because others have doubts or need to be convinced. If only a statement is meant, 'behaupten' is more suitable. If someone strongly emphasizes their honesty or innocence, 'beteuern' is more precise.
