How do you form indirect speech in Latin?
RULE 1: Indirect Statement = Accusative Subject + Infinitive Verb [There is no "that" in Latin!] Unlike with participles, Latin has a full set of infinitives, that is, all six which are possible, encompassing both voices (active/passive) and all three tenses (past/present/future).
How does Latin form indirect discourse?
Indirect statements in classical Latin usually use the accusative and infinitive construction. In this the main verb of the quoted sentence is changed to an infinitive, and its subject to the accusative case; this construction is also sometimes used for commands and rhetorical questions.
