===''Exordium''===
The ''exordium'' ({{IPAc-en|ɛ|ɡ|ˈ|z|ɔr|d|i|ə|m}}; meaning "beginning" in [[Latin]]; from ''exordiri'', meaning "to begin") was the introductory portion of an oration. The term is Latin and the Greek equivalent was termed the ''[[proem]]'' or ''prooimion''.

In the ''exordium'', the orator states the purpose of the discourse. In doing this, they need to consider several things:

* What kind of cause is he presenting? For instance, is it an honorable cause (defense of a hero) or a dishonorable one (defense of a murderer)?
* Should a direct beginning be favoured, or should the beginning be more subtle and indirect? 
* In what manner ought the speaker to proceed (e.g., humorously or seriously)?
* The speaker should introduce their own character or credentials, so as to make the audience predisposed to believing their arguments.
* If required, or possible, the speaker might also question the character or credentials of his opponent.
* Lastly, the speaker must avoid certain faults in the introduction. For example, this excerpt from the Roman ''[[Rhetorica ad Herennium]]'' lists several faults:

<blockquote>In the Introduction of a cause we must make sure that our style is temperate and that the words are in current use, so that the discourse seems unprepared. An Introduction is faulty if it can be applied as well to a number of causes; that is called a banal Introduction. Again, an Introduction which the adversary can use no less well is faulty, and that is called a common Introduction. That Introduction, again, is faulty which the opponent can turn to his own use against you. And again that is faulty which has been composed in too laboured a style, or is too long; and that which does not appear to have grown out of the cause itself in such a way to have an intimate connection with the Statement of Facts; and, finally, that which fails to make the hearer well disposed or receptive or attentive.
: —''Rhetorica ad Herennium'', I. vii, 11, trans. Harry Caplan, Loeb Classical Library, 1954.)</blockquote>

In short, the ''exordium'' was the portion of the discourse in which the orator would prepare the audience to hear his arguments in a favorable mindset. "An exordium can serve different kinds of functions in the differing species of rhetoric, but in all of them some of the major themes of the coming discourse will be announced in advance".<ref>{{Cite book|title=Letters and Homilies For Hellenized Christians |volume=II |last=Witherington |first=Ben III |publisher=IVP Academic |year=2007 |isbn=978-0-8308-2933-0 |location=Downers Grove, Illinois |pages=297}}</ref>
