Rhetorical devices are the nuts and bolts of speech and persuasive writing; the parts that make a communication work. Separately, each part of is meaningless, but once put together, they create a powerful effect on the listener/reader.

2. Parallelism
Parallelism is the use of components in a sentence that are grammatically the same; or similar in their construction, sound, meaning or meter.
Writing structures that are grammatically parallel helps the reader understand the points better because they flow more smoothly.

3. Hypophora
A common technique is to start a speech with a hypophora, in which the speaker first asks a question and then answers it.
In many political speeches, the word Why is used regularly as an obvious signpost of the speaker’s intention to give his audience answers.

4. Repetition
Repetition can be effective in creating a sense of structure and power. In both speech and literature, repeating small phrases can ingrain an idea in the minds of the audience.

5. Antithesis
a figure of speech in which an opposition or contrast of ideas is expressed by parallelism of words that are the opposites of, or strongly contrasted with, each other, such as “hatred stirs up strife, but love covers all sins”
Obama is famous for having said “There are no red states or blue states. There are only the United States of America.”
"It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair, we had everything before us, we had nothing before us, we were all going direct to Heaven, we were all going direct the other way." (Dickens, A Tale of Two Cities)

6. Figurative speech
People like to think in metaphors. The image of bending the arc of history up towards hope is powerful. Figurative speech tends to work best when set off by concrete images.

We shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our island, whatever the cost may be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills. We shall never surrender."
(British Prime Minister Winston Churchill)

8. Epistrophe
Repetition of the same word or phrase at the end of successive clauses.

"It was whispered by slaves and abolitionists as they blazed a trail towards freedom through the darkest of nights: Yes, we can.
"It was sung by immigrants as they struck out from distant shores and pioneers who pushed westward against an unforgiving wilderness: Yes, we can.
(Barack Obama)

9. Tricolon
