zweifeln vs hoffen
to hope
'hoffen' and 'zweifeln' show different attitudes toward an uncertain situation. 'hoffen' is positive: you wish that something good will happen or become true. 'zweifeln' is uncertain or skeptical: you are not sure that something is true or will work out. People often say 'an etwas zweifeln' (to doubt something). The words can be confused because both are used in situations of uncertainty. The difference is: 'hoffen' looks ahead with confidence, while 'zweifeln' shows doubts or concerns.
