language post: subjunctive

In my opinion, one of the hardest things about Spanish is learning the subjunctive tense. I think that this is because in English, we don't have anything similar that we use on a daily basis. Therefore, we can't have anything to compare it to, or anything to link it to. But I managed to memorize when it was used and how to use it. Something I never learned in high school Spanish, however, was how to create the future subjunctive. For example, if I wanted to say "I hope i studied enough" I would have to use the subjunctive for the verb "to study".  This is how it would look in Spanish:

"espero que estudiera suficiente." 

In order to change the verb "estudiar" to the past subjunctive, the verb is put into the third  person, with the -ron taken off. -a, -as, -a, -amos and -aron are then added, depending on the noun.

The imperfect subjunctive can also be used to describe things that could possibly happen in the future. this is most commonly used with sentences beginning with "if".  For example, if I wanted to say, "If I have kids one day...." I would have to use the future subjuntive for "to have" because there is a slight chance it would not happen. It would look like this:

"si tuviera hijos algun día..."

Because it is not a definite statement, the future subjunctive is used to express uncertainty.
