[Rusty]

Rusty, I don't remember one word: I wonder

What does it mean, or how can I use it?

I guess that it means Creo.:sad:

I appreciate your answer.

Creo = I think, or I believe
Me pregunto = I wonder

Also, when you use the future tense in Spanish to 'ask rhetorical questions', the English translation is wonder.
¿Lloverá mañana? = I wonder if it'll rain tomorrow.

[Tomisimo]

to wonder:

1. preguntarse - Me pregunto se vendrá. = I wonder if she'll come.
2. desear saber - Deseo saber si el avión llegará a tiempo. = I wonder if the plane will be on time.
3. hacer pensar - Me hizo pensar. = He left me wondering.
4. pensar si le conviene a uno hacer algo - Estoy pensando si me conviene comprar un coche. = I'm wondering about buying a car.

The two usages that Rusty mentions are probably the most common.
