Frequently Asked Questions

Is 'dudo' always followed by the subjunctive?

Yes, when 'dudo' is used in the affirmative ('I doubt that...'), it nearly always requires the subjunctive (the uncertainty verb form) in the clause that follows. However, if you say 'No dudo que...' (I don't doubt that...), you are expressing certainty, and the indicative (normal verb form) is usually required.

What is the difference between 'dudar' and 'preguntar'?

'Dudar' means 'to doubt' or 'to be unsure.' 'Preguntar' means 'to ask a question.' You might use 'dudo' if you feel skeptical about a fact, and then 'pregunto' to ask for clarification.
