1730. The subjunctive is sometimes used in relative, temporal, or
conditional sentences, to express action repeated or occurring at no
particular time: as,
(_a._) #neque aliter sī faciat, ūllam inter suōs habet auctōritātem#, 6,
11, 4, _and if he does not do this, he never has any ascendancy at all
over his people_. With the present and perfect, however, this
subjunctive is confined principally to the indefinite second person
singular (1030): as, #bonus sēgnior fit, ubī̆ neglegās#, S. _I._ 31, 28,
_the good man always gets slacker, when you are neglectful_. #sīquoi
mūtuom quid dederīs, fit prō propriō perditum#, Pl. _Tri._ 1050, _if
you’ve lent anything to any man, ’tis not your own, but lost_. (_b._)
The imperfect and pluperfect subjunctive begin with Catullus and Caesar,
and get to be common with Livy and Tacitus: as, #sī quis prehenderētur,
cōnsēnsū mīlitum ēripiēbātur#, Caes. _C._ 3, 110, 4, _every time a man
was taken up, he was rescued by the joint action of the rank and file_.
#quemcumque līctor prēndisset, tribūnus mittī iubēbat#, L. 3, 11, 2,
_every man the lictor arrested, a tribune would order released_.
