hinterfragen vs prüfen
to check / test
'prüfen' and 'hinterfragen' both mean that you do not simply accept something without checking it. 'prüfen' is neutral: you check something or carefully consider a possibility. 'hinterfragen' is more critical. You ask about the reasons, motives, or legitimacy of something. Learners may confuse the words because both have to do with careful thinking. 'prüfen' is appropriate when you want to determine certainty or correctness. 'hinterfragen' is appropriate when you have doubts or want to view something critically.
