Hörensagen vs Erfahrung
experience
'die Erfahrung' and 'das Hörensagen' stand in clear contrast to each other. With 'Erfahrung', you have experienced something yourself, tried it out, or learned it through your own practice. With 'vom Hörensagen' (by hearsay), you know something only because others have told you about it. That is often less certain. Learners may confuse the words when speaking generally about knowledge. The source is important: if the knowledge comes from your own experience, it is 'Erfahrung'. If it comes only from other people's accounts, it is 'Hörensagen'.
Hörensagen
Den neuen Arzt kenne ich nur vom Hörensagen.
I know the new doctor only by hearsay.
Erfahrung
Aus eigener Erfahrung weiß ich, dass der Weg im Winter gefährlich sein kann.
From my own experience, I know that the route can be dangerous in winter.
