bestätigen vs beweisen
to prove
'bestätigen' and 'beweisen' both have to do with truth or correctness. 'bestätigen' means that you say or show: That is correct, the appointment is valid, the information is right. Often a message, a reply, or a second observation is enough for this. 'beweisen' is stronger: You show the truth with clear facts, evidence, or arguments. Learners may confuse the words because both make a statement more certain. As a guide: 'bestätigen' often fits with appointments, receipt, or impressions; 'beweisen' fits when you really have to provide proof.
