In Greek grammar, Subjunctive refers to a mood that generally expresses various states of unreality such as doubt, possibility, necessity, or action that has not yet occurred. The greek language has a rich grammatical system with various verb tenses which gives it a level of expressivity hard to find in other languages. One of these tenses is the subjunctive. It is used in a variety of contexts, such as desires, doubts, orders, and possibilities that may or may not occur. Mastery of Subjunctive is crucial for having a good command of Greek language.
