—EMILIA PARDO BAZÁN.
I was wondering if I should have time to go before they came.
Yo me preguntaba si tendría el tiempo de ir antes que llegasen ellos.
I wonder who did this.
Yo quisiera saber quién habrá hecho eso.
The verb to wonder is, however, often best translated by the future of probability, as illustrated in the following examples:
Has he come yet, I wonder?
I wonder if it is time yet.
¿Será ya la hora?
