verifizieren vs bestätigen
to confirm
'bestätigen' and 'verifizieren' both have to do with recognizing something as correct. 'bestätigen' is more general and works well in everyday life, for appointments, messages, or simple information. 'verifizieren' means more specifically: you check something and then establish that it is correct or genuine. It sounds more formal and is often used in technology, science, or administration. Learners may confuse the words because both have to do with truth. As a simple guide: a person or office can confirm something; with 'verifizieren', the checking process is more in focus.
