Confusing Words

compare to vs compare with

Compare to' and 'compare with' are often used interchangeably, but in careful writing they carry subtly different meanings.

  • compare to — compare to' is used when you are drawing a likeness between two things — highlighting a similarity between them — for example, ‘The reviewer compared the novel’s structure to a jigsaw puzzle, where each chapter is a piece.’
  • compare with — compare with' is used when you are examining similarities and differences between two things, analysing them side by side — for example, ‘The study compared the literacy rates of urban schools with those of rural schools over a five-year period.’

Memory rule: Compare to points out a likeness; compare with sets up a two-sided analysis. In academic writing, compare with is the more common and precise choice.
