Question

Explain why the expression dudo que takes the subjunctive while no dudo que does not in 2-3 sentences

Answer 1

The expression "dudo que" (I doubt that) takes the subjunctive because it expresses uncertainty or doubt regarding the action that follows. In contrast, "no dudo que" (I don't doubt that) implies belief or certainty about the action, which allows for the use of the indicative mood instead. This distinction reflects the speaker's attitude toward the truth of the statement being made.
