Spanish Grammar: Expressing doubts or uncertainty (B1)

No creo que vaya a usarlo.

In Spanish, we are going to use the subjunctive after verbs expressing doubts or uncertainty (check present subjunctive conjugation), and verbs saying what you think about something that is used with “no”. Here you have some examples:

No creo que sea importante. (I don’t believe it’s important.)

No pienso que esté bien. (I don’t think it is right.)

Dudo que tenga tiempo. (I doubt I have time.)

No pienso que entiendan. (I don´t think they understand.)

No estoy seguro que Olga venga. (I am not sure that Olga is coming.)

But we would say

Creo que es importante. (I believe it’s important.)

Pienso que está bien. (I think it is right.)

No dudo que tendré/tenga tiempo. (I don’t doubt I have time.)

Pienso que entienden. (I think they understand.)

Estoy seguro que Olga vendrá. (I am sure that Olga is coming.)

Impersonal expressions that show certainty  when they’re negated also require the subjunctive

  • no es cierto (it is not certain, it is not sure)
  • no es claro (it is not clear)
  • no es evidente (it is not evident)
  • no es exacto (it is not exact)
  • no es obvio (it is not obvious)
  • no es seguro (it is not sure)
  • no es verdad (it is not  true)
  • no parece (it doesn’t seem)

No es cierto que Fernando y Marta se vayan a divorciar. (It is uncertain that Fernando y Marta they are going to divorce.)

No es seguro que vengan mañana. (It is not sure they come tomorrow.)

No parece que esté preocupado (It doesn’t seem to be worried.)
