Dudar and Prepositions
When you doubt a person or a fact, you usually need the preposition de (of/about): 'Dudas de lo que dice.' (You doubt what he says.)
Doubt and Subjunctive
The verb dudar (to doubt) often requires the next verb to be in a special form called the Subjunctive, because it expresses uncertainty: 'Dudo que él venga.' (I doubt that he comes.)
❌ Common Pitfalls
Forgetting 'de'
Mistake: "Dudas su palabra."
Correction: Dudas de su palabra. (The verb *dudar* often demands the preposition *de*.)
⭐ Usage Tips
Action vs. Belief
Use dudar en when you are hesitating before an action ('Dudas en saltar'). Use dudar de when you question a truth or belief ('Dudas de la historia').
