Paraphrasing

How to paraphrase “decrease” well

  • Match the verb to the size of the change: dip for small and temporary, decline for gradual, plunge or plummet for sudden and large.
  • Use the noun pattern for variety: 'There was a steady decline in coal use' or 'Coal use saw a steady decline'.
  • Watch transitive verbs. Reduce, cut and lower need someone doing the action; charts usually need fall, drop or decline.

Band tip: the public IELTS Writing band descriptors for Lexical Resource describe Band 7 as using “less common lexical items” with “some awareness of style and collocation”. A synonym that changes your meaning or breaks a collocation works against you, so choose the word that fits the sentence, not the rarest one you know.

In context

Use it in an answer

Writing Task 1 (invented bar chart: daily newspaper sales in one country, 2000 to 2020)Written by BandLadder

Sales of printed newspapers declined throughout the period, falling from 12 million copies a day in 2000 to just under 5 million in 2020. The sharpest change came between 2008 and 2010, when sales plunged by almost a third. Free newspapers followed a different path: their circulation dipped in 2009 but then held steady at around 1.5 million.

Frequently asked questions

What can I use instead of decrease in IELTS Task 1?+

Fall and drop are the neutral swaps. Decline suits a gradual fall, dip a small temporary one, and plunge or plummet a sudden large one. Choose by the size and speed of the change you see.

Is 'reduced' correct for a chart?+

Only with an object or in the passive: 'The council reduced fees' or 'Fees were reduced'. 'Fees reduced' on its own is a common error; write 'fees fell'.

What is the difference between plunge and plummet?+

Both describe a sudden large fall. Plummet suggests an even faster, steeper fall. Either is fine once in a report, for the most dramatic change only.

Can I use dip for a big fall?+

No. Dip means a small fall that usually reverses. For a large fall use drop sharply, plunge or plummet.
