[II. PROTASES OF ACTION NON-OCCURRENT.]
[2091.] A conditional period in which the non-occurrence of the action is implied takes the imperfect or pluperfect subjunctive both in the protasis and in the apodosis. The imperfect usually denotes present or indefinite time, and the pluperfect denotes past time.
For the present subjunctive in such conditions, see [2075].
[2093.] The imperfect sometimes denotes past time ([1559]). When future time is referred to, the protasis is usually in the imperfect of the periphrastic future, commonly the subjunctive, but sometimes the indicative ([2108]).
[2093.] The apodosis is very rarely in the present subjunctive ([2098]). The periphrastic future is sometimes used, commonly in the indicative ([2097], [2100]).
[(1.) Protasis in the Imperfect Subjunctive.]
(a.) Apodosis in the Imperfect Subjunctive.
(a.) Protasis and apodosis both denoting present action; this is the usual application: sī intus esset, ēvocārem, Pl. Ps. 640, I should call him out, if he were in. is iam prīdem est mortuus. sī vīveret, verba eius audīrētis, RC. 42, that person has long been dead; if he were alive, you would hear his evidence. adnuere tē videō; prōferrem librōs, sī negārēs, DN. 1, 113, I see you nod assent; I should bring out the books, if you maintained the opposite. sī L. Mummius aliquem istōrum vidēret Corinthium cupidissimē trāctantem, utrum illum cīvem excellentem, an ātriēnsem dīligentem putāret? Par. 38, if Mummius should see one of your connoisseurs nursing a piece of Corinthian, and going into perfect ecstasies over it, what would he think? that the man was a model citizen or a thoroughly competent indoor-man? quod sī semper optima tenēre possēmus, haud sānē cōnsiliō multum egērēmus, OP. 89, now if we could always be in possession of what is best, we should not ever stand in any special need of reasoning.
