the Present Subjunctive
In Portuguese there are several ways to talk about the future, each with varying shades of meaning. The present subjunctive is used to show that some idea or action is hypothetical. For example,
I hope that you have a pair of sunglaases is hypothetical. So is, Do you want me to speak to her?
HYPOTHETICAL situations include those that express desire, emotion, improbability, give commands, and to express opinion.
TRIGGERS: espero que; caso que; é importante que; é possivel que; é necessário que; get the idea?
