In order to write and/or deliver a successful speech, you must be able to understand and skillfully use rhetoric. ‘Rhetoric’ is the art of persuasive speaking; it was first developed in Ancient Greece and is still used by politicians, businessmen, and leading professionals in almost any field of work in the present day.

A personal story, either your own or about someone you know. It must be told in a way that sets a persuasive example.

E.g. ‘When I was a little child, I used to think…. ‘

‘My friend had this problem a few years ago…’


Repeating the beginning of a sentence several times for effect — this amplifies your point and connects several ideas together.

E.g. Nothing will grow here, if we do not change the way we treat the earth. There will be no trees. There will be no birds. There will be no humans either, because we all depend on ecosystems to exist.


An over-exaggeration of a statement in order to create a more sensational, emotional and emphatic point about something. It can be comedic, or used to stress an important idea. Hyperbole is always factually inaccurate.

Humour — using puns, irony and other comedic techniques in order to make the audience at ease, more trusting of your ideas and in a relaxed, entertained mood. Not every speech requires humour — make sure to understand the right tone and style required for your audience and topic before using this technique.


She’s got worse fashion sense than my grandma.

Sure, skiing is fun, but have you ever tried filing your tax return at two minutes to the deadline? That’s a really wild ride.


Idioms, or idiomatic expressions, are phrases which can’t be directly translated because they don’t literally mean what they say. We use them figuratively as an expression or figure of speech to create an informal, conversational, friendly and familiar tone. They can also sometimes be humorous.


The manager has got a screw loose.

That failure was actually a blessing in disguise.

Rhetorical question

A question that doesn’t require an answer, either because it opens up the audience’s mind and makes them think deeper about something, or because the answer is very obvious in the first place. A highly persuasive technique that is used to get the audience on your side about a particular issue.


We’ve all experienced difficulty at some point in our lives, haven’t we?

Asking a rhetorical question, and then answering it yourself. It can be even more effective than a standard rhetorical question.

building up tension but having an underwhelming and unexpected ending. This is a frustrating technique that can be used to create empathy or sympathy, as well as humour, sadness or disappointment — a highly emotive technique.


He hit me. Right in the face. And do you know what I did? Nothing.

So I spent five days straight awake, powered only by coffee and chocolate bars, manically typing my essay to make sure it was due on time. I missed football in the park with my friends.

Syndetic listing (using conjunctions between listed items): The feast was huge! They had roast chicken and steaks and burgers and chips and garlic bread and salads and coleslaw and apple pie and ice cream. — creates an extended, drawn out feeling, each image in the list is emphasised.

Facts and figures

it’s very hard to deny someone’s opinion when they have a lot of factual evidence to back it up. This can include definite facts or statistics and numbers. The more detailed and specific you are, the more convincing this technique will be.
