vertrauenswürdig vs ehrlich
honest
'ehrlich' and 'vertrauenswürdig' both describe people or information that one can believe. 'ehrlich' mainly emphasizes that someone tells the truth and does not lie or cheat. 'vertrauenswürdig' is somewhat broader: you can rely on a person, a source, or an institution. Learners may confuse the words because honesty is an important reason for trust. But someone can be honest without you immediately giving them a lot of responsibility. 'ehrlich' fits especially when talking about truth and character, while 'vertrauenswürdig' is more about trust, safety, and reliability.
vertrauenswürdig
