1721. The indicative is ordinarily used in sentences introduced by a
relative pronoun, or by a causal conjunctive word other than #cum#.
#pontem, quī erat ad Genāvam, iubet rescindī#, 1, 7, 2, _he orders the
bridge which was near Geneva torn up_. #concēdō, quia necesse est#,
_RA._ 145, _I give up, because I have to_. In sentences of this class,
however, the subjunctive is often required, particularly in indirect
discourse (1722), or in cases of attraction (1728).
