Mixed Conditionals (past cause → present result)

Module 10 gave two PURE unreal conditionals: present-unreal (αν + imperfect, θα + imperfect - untrue NOW) and past-unreal (αν + pluperfect, θα + pluperfect - untrue THEN). A MIXED conditional CROSSES them: a changed PAST would have changed the PRESENT - a past-unreal condition feeding a present-unreal result. «Αν είχα διαβάσει, θα ήξερα την απάντηση» (“if I had studied [then], I would know the answer [now]”). Each tier keeps its own tense: the CONDITION is past-unreal (αν + PLUPERFECT - αν είχα διαβάσει, αν με είχες βοηθήσει); the RESULT is present-unreal (θα + IMPERFECT - θα ήξερα, θα ήμουν). «Αν είχα φύγει, θα ήμουν σπίτι τώρα» - the τώρα (“now”) makes the present result plain. Contrast the PURE past-unreal, which keeps BOTH halves pluperfect (θα είχα περάσει - a wholly past outcome): the RESULT tense tells you whether the imagined consequence lands in the past (θα + pluperfect) or in the present (θα + imperfect). Choose the result tier by WHEN the consequence would be felt.
