Sorry, I spelled it wrong. Subjuntivo. It's what all you guys use naturally and it's the bane of anyone who doesn't have it in their grammar (the french for instance do).
Here's the wikipedia article for it: https://es.wikipedia.org/wiki/Modo_subjuntivo
@Takakage Not only old style, it gets used in present tense quite a bit. And to find out when is a pain in the ass. My wife uses it everyday naturally, if I ask her why, she just shrugs... I'm sure for you it's the same
@semd3 I took courses twice a week at uni (1,5 hours each time) for around 2 years to get there. If you really put time and effort into it, it can go a lot quicker of course. But to a native spanish speaker I still do sound like a foreigner, because I know how to express myself, but my grammar often is just completely wrong. Not taking classes for over 3 years doesn't help of course.
