Colloquial probability (capaz que)

In Latin America, a common colloquial way to say "maybe," "perhaps," or "might" is the phrase capaz que.

maybe / perhaps
capaz que

Capaz que can be followed by either the present indicative or the present subjunctive, depending on your level of certainty.

Capaz que + Indicative Use the indicative when the possibility feels likely, or when making a confident guess based on the current situation.

Maybe the sky will clear up today and we'll see the phenomenon.
Capaz que el cielo se despeja hoy y vemos el fenómeno.
Maybe if you point the telescope toward that constellation, you'll see something.
Capaz que si apuntas el telescopio hacia esa constelación, ves algo.

Capaz que + Subjunctive Use the subjunctive when there is more doubt, or for hypothetical scenarios.

Maybe the sky will clear up before dawn.
Capaz que el cielo se despeje antes del amanecer.
Maybe a meteor will cross the sky tonight.
Capaz que un meteoro atraviese el cielo esta noche.

While formal Spanish often relies on tal vez or quizás, capaz que is the perfect everyday alternative for a casual guess.
