LESSON  XXXVIII

CONDITIONAL   SENTENCES   IN  INDIRECT   DISCOURSE

207.   The subject of conditional sentences in indirect dis¬
course will present no difficulties if such sentences be regarded
as fixed forms subjected to a uniform external force — the verb
of quotation — producing, of course, fixed results. That is,
the same class of condition always appears in the same form in
indirect discourse.

208.   Changes in form of conditional sentences in passing
from direct to indirect discourse.

a.   Changes in protasis.

All protasis verbs stand in the subjunctive in Latin in indirect
discourse, obeying the law of sequence of tenses, except that
the tenses of contrary to fact conditions can never become
primary.

b.   Changes in apodosis.

All apodosis verbs, except those of commands and prohi¬
bitions, will become infinitive forms, as follows:

1.   All indicatives become infinitives, the tense of which is
determined by 196, a.

2.   All active subjunctives become future infinitives or the
substitute form, fore with ut and the subjunctive, except that
in the past contrary to fact condition the apodosis is expressed
by a compound infinitive formed by joining fuisse to the future
participle of the verb; but if the verb has no supine stem, use
futurum fuisse followed by ut and the imperfect subjunctive.

3.   All passive subjunctives become fore (futurum esse) fol¬
lowed by a clause with ut and the subjunctive; except that in
the past contrary to fact condition futurum fuisse is substituted
for fore.
