Learn Spanish (Spain): Quizás la situación cambie pronto. - Maybe the situation will change soon.

Words like quizás (maybe or perhaps) express doubt or uncertainty. In Spanish, when you use quizás to talk about something that might happen in the future, you usually use the present subjunctive (cambie) rather than the future tense.

Could I use the normal present cambia or future cambiará here instead?

Yes, you can. With quizás, using the subjunctive (cambie) shows a higher degree of doubt. If you use the indicative (cambia or cambiará), it signals that you feel more certain the situation will actually change. Both are correct, but the subjunctive is very common for guesses.

Is there a difference between quizás and quizá?

No, they mean exactly the same thing and can be used interchangeably. Quizás is sometimes preferred before a word that starts with a vowel to make pronunciation smoother, but here before the consonant in la, both quizás and quizá are perfectly natural.

Since cambiar is a regular verb, how do we build the subjunctive form cambie?
