What Is Decorum?
Decorum (the accommodating of the words to the audience) is a central rhetorical concept requiring one’s words and subject matter to be aptly fit to each other, to the circumstances and occasion (kairos), the audience, and the speaker.
In sum, decorum is the capacity to shape the words appropriately to the audience, in order that they might understand the message.
Using Decorum for Effective Delivery
Although initially just one of several virtues of style (aptum), decorum has evolved to become the most rhetorical of rhetorical concepts, an idea that permeates the whole of classical rhetoric, and an important point of convergence for the social, moral, and aesthetic concerns of the rhetorical tradition. Essentially, if one’s ideas are appropriately embodied and presented (thereby observing decorum), then one’s speech will be effective. Conversely, rhetorical vices are breaches of some sort of decorum.
Decorum is properly associated with harmony, grace, and comeliness as well as timeliness and appropriateness, just as the beauty of nature is associated with its rational design. Decorum has been a controlling principle in correlating certain rhetorical genres or strategies to certain circumstances.
