The Subjunctive Mood is used basically to express wish, hope, expectation, intentions, and also to make suggestions and negative commands. It is the verb form of possibility, because it indicates something that "should" or "might" take place. If is always used in "when" and "if" clauses because those are things that might happen but in those clauses, the "should" or "might" need not be added because we understand that the clause is just a possibility.  

The DELIBERATIVE subjunctive is used when a speaker is asking himself or herself a question about what to do or what to say). Common characteristics of the deliberative subjunctive are:

• It is used only in the PRESENT or AORIST tense
• It is used only in the 1st PERSON
• The negative is μή
