Writing for impact: antithesis, parenthesis and more

The specification gives three examples of rhetorical devices: rhetorical questions, antithesis and parenthesis. Used with control, these and a few others make your writing memorable.

Antithesis

Two contrasting ideas set in a balanced structure.
'We can choose to act today, or we can choose to apologise tomorrow.'
'Not a cost to be cut, but an investment to be made.'
Effect: the balance makes your choice sound obvious and memorable.

Parenthesis

Extra information dropped into a sentence, marked off by a pair of brackets, commas or dashes.
'The new car park (which cost the town two million pounds) stands empty.'
'My grandmother, a nurse for forty years, has seen it all.'
Effect: adds a sharp aside, a fact or a touch of humour without breaking the flow.
Check: the sentence must still make sense if you remove the parenthesis.

Four more for impact

DeviceExampleEffect
Anaphora'We will rebuild. We will recover. We will return.'Repeated openings build rhythm and determination
Hypophora'Why does this matter? Because...'Asks a question then answers it, guiding the reader
Tricolon'faster, cheaper, cleaner'A group of three feels complete
Analogy'A school without a library is like a kitchen without food.'Explains an idea through a familiar comparison
Worked example

Improve this sentence using parenthesis and antithesis: 'The park should stay open.'

  1. Add parenthesis with useful detail: '(the only green space for two miles)'.
  2. Add antithesis: 'not a luxury, but a lifeline'.
  3. Combine smoothly.

Answer: The park (the only green space for two miles) is not a luxury, but a lifeline, and it must stay open.

Key idea

Antithesis balances opposites; parenthesis adds an aside in brackets, commas or dashes; anaphora, hypophora, tricolon and analogy add rhythm and clarity. Use a few deliberately rather than many mechanically.

Key words
Antithesis
Placing opposite ideas side by side in a balanced structure, as in 'not a burden, but a gift'.
Structure
