2232. The future infinitive is only used as a representative of the
indicative, and not as a substantive.
2233. For the future infinitive active or passive, a circumlocution with
#fore# or #futūrum esse# with #ut# and the subjunctive present or
imperfect is often used. This construction is necessary when the verb
has no future participle or supine: as,
#spērō fore ut contingat id nōbīs#, _TD._ 1, 82, _I hope we may be so
fortunate_. #clāmābant fore ut ipsī sē dī ulcīscerentur#, _V._ 4, 87,
_they cried out that the gods would avenge themselves_.
2234. #fore# with the perfect participle of a passive or deponent,
represents the future perfect of direct discourse: as, #dēbellātum mox
fore rēbantur#, L. 23, 13, 6, _they thought the war would soon be over_.
2235. (1.) The future infinitive is commonly used with #iūrō#, #minor#,
#polliceor#, #prōmittō#, and #spērō#, especially when the leading verb
and the infinitive have the same subject: as,
#iūrāvit sē nisi victōrem in castra nōn reversūrum#, Caes. _C._ 3, 87,
5, _he swore he would not come back to camp except as a victor_. #quod
sē factūrōs minābantur#, Caes. _C._ 2, 13, 4, _which they threatened
they would do_. #obsidēs datūrōs pollicitī sunt#, 4, 27, 1, _they
volunteered to give hostages_.
2236. (2.) A looser present infinitive is sometimes used with the above
verbs, especially in old Latin, generally without a subject accusative.
Thus with #iūrō# by Cato and Plautus, and with #minor#, _proclaim with
threats_, by Lucretius. Similarly #dare pollicentur#, 6, 9, 7, _they
offer to give_. #reliquōs dēterrērī spērāns#, Caes. _C._ 3, 8, 3,
_hoping that the rest were scared_. #spērō nostram amīcitiam nōn egēre
testibus#, _Fam._ 2, 2, _I trust our friendship needs no witnesses_. As
#possum# has no future infinitive, the present of this verb is
necessarily used: as, #tōtīus Galliae sēsē potīrī posse spērant#, 1, 3,
8, _they hope to be able to get the control of the whole of Gaul_.
