DOUBT in Spanish: DUDA
Duda · noun · DOO-dah
Duda is the Spanish noun for doubt, and it appears in one of the most useful classroom phrases any Spanish learner should know: ¿Tienes alguna duda? meaning Do you have any questions? This usage is broader than English doubt, since duda in Spanish covers both skeptical doubt and simple questions or uncertainties. The verb form dudar follows a regular -ar pattern and is notable for triggering the subjunctive mood in dependent clauses.
DOO-dah
No tengo ninguna duda de que vas a aprobar el examen.
I have no doubt that you are going to pass the exam.

Avoid These Mistakes When Using Duda
Missing the subjunctive after dudar
Incorrect: Dudo que él viene mañana.
Correct: Dudo que él venga mañana.
Dudar que triggers the subjunctive mood in Spanish, requiring venga instead of the indicative viene, because doubt introduces uncertainty.
Using duda for a factual question
Incorrect: Tengo una duda: ¿Dónde está el baño? (slightly unusual)
Correct: Tengo una pregunta: ¿Dónde está el baño?
While duda is widely used for questions in classrooms, for straightforward factual questions like asking for a location, pregunta sounds more natural.
