original sentence had a future indicative or potential subjunctive ('would do'), the indirect statement has a future participle combined with ( is however often omitted): (Cicero) 'I heard that Valerius was due to arrive today' One verb, 'I am' has its own future infinitive , which may be used instead of . The verb 'I am able' on the other hand has no future infinitive or future participle. The future participle combined with , which expresses a past or present potential ('would be doing' or 'would have done'): (Cicero) '(he said that) if he had not been tired from the journey, he would have come to us straightaway' Three other tenses are found in indirect statements: the supine with , the perfect participle with , and the perfect participle with . However, these are rare. The main verb introducing indirect statements does not have to be a verb of speaking; it can also be any of a range of other verbs, such as 'he realised', 'he pretended', 'it is well known', 'I hope', 'he wrote' and so on, which use the same construction. The infinitive is used only for the main verb in an indirect statement; any other verbs are changed into the subjunctive mood, using one of the past tenses if the context is past: (Nepos) '(he told them that) they would easily find the place where he was' Indirect question Another kind of indirect speech is the indirect question, in which the verb is usually changed into the subjunctive mood: (Catullus) 'do you ask why I do this, perhaps?' When the context is past, one of the past tenses of the subjunctive is used (imperfect or pluperfect). (There are some exceptions to this rule, however.) (Cicero) 'I told them what he had done that night' Indirect command The third main type of indirect speech is the indirect command, for which two constructions are possible. Some verbs, principally the verb 'I order' and its opposite 'I forbid', use the accusative and infinitive construction, often with a passive infinitive: (Caesar) 'he ordered the signal to be given' Most other verbs use a clause introduced by the conjunction or (if negative) followed by a subjunctive verb. As with indirect questions, the tense of the subjunctive depends on whether the context is present or past. A present context requires the present subjunctive: (Cicero) 'he is encouraging me to write to the Senate'
