Real vs Unreal Conditionals - the Whole System

Greek has THREE conditional patterns, and the verbs tell you which world you are in. (1) REAL / open (a live possibility) - αν + PRESENT, θα + FUTURE: Αν έχω χρόνο, θα διαβάσω (“If I have time, I’ll read”). (2) PRESENT-UNREAL (contrary to fact now) - αν + IMPERFECT, θα + IMPERFECT: Αν είχα χρόνο, θα διάβαζα (“If I had time, I’d read”). (3) PAST-UNREAL (contrary to fact then) - αν + PLUPERFECT, θα + PLUPERFECT: Αν είχα διαβάσει, θα είχα περάσει (“If I had read, I’d have passed”). αν always opens the condition and θα always sits in the result; what shifts is the TENSE pair - present/future for the real, imperfect/imperfect for the unreal-now, pluperfect/pluperfect for the unreal-then.
