 The indicative and subjunctive conditionals above differ from each other only in particular details of their linguistic form. It is therefore plausible to explain their contrasting semantic behavior in terms of the semantics of those linguistic differences. Indicatives, like  (3)  and  (5),  feature verbs in the simple past tense form, and no modal auxiliary in the consequent. Subjunctives, like  (4)  and  (6),  feature verbs in the past perfect (or “pluperfect”) with a modal would in the consequent. Something in the neighborhood of these linguistic and semantic differences constitutes the distinction between indicative and subjunctive conditionals—summarized in  Figure 1.[3]
