Generally the longer forms of the imperative are used (1577): #patrōnus
sī clientī fraudem fēcerit, sacer estō#, Twelve Tables in Serv. to V. 6,
609, _if a patron shall cheat his client, let him be doomed_. #servītum
tibi mē abdūcitō, nī fēcerō#, Pl. _Ps._ 520, _if I don’t do it, take me
off to be your slave_. #hoc sī effēceris, quodvīs dōnum ā mē optātō#, T.
_Eu._ 1056, _if you do this, ask any gift you please of me_. #sī mē
adsequī potueris, ut tibī̆ vidēbitur, sepelītō#, _TD._ 1, 103, _if you
can ever find me, then bury me as you think best_. Rarely the shorter
forms: #inpinge pugnum, sī muttīverit#, Pl. _B._ 800, _drive your fist
into him if he says booh_. #sī tumidōs accēdere fastūs sēnseris, inceptō
parce referque pedem#, O. _AA._ 1, 715, _if thou shalt see disdain come
swelling high, give o’er and beat retreat_.
