Suffixes in Verbs : -ise or -ize

-ise or -ize in British English & American English?



It is generally true that the American preference for
-ize is mirrored in British English by a general preference for -ise, so it is perhaps useful to standardise on one of these two patterns as far as possible. In a standard British dictionary - e.g. the Concise Oxford - you will often find that both options are possible in British English.

  • realise or realize


  • organsise or organize


  • Whilst for other entries -ize is listed as unmistakably American.

  • analyse = British English


  • analyze = American English



  • Those who have a preference for British English in this respect, for the sake of consistency can retain this preference for other spelling options, e.g.

  • programme, not program


  • colour, not color


  • metre, not meter


  • catalogue, not catalog


  • traveller, not traveler


  • When you are reading American English, it can be fun to spot the differences.
