Realise or Realize—Which Should I Use?

People associate a lot of things with British culture—one of them is how different British English is from American English, spelling included. Let’s compare realise and realize.

Consider your audience. For American readers, the -ize ending is probably the way to go. While both endings might be correct according to your dictionary of choice, you could unnecessarily alienate your audience if you insist on using -ise. Elsewhere, preferences might not be as strong, but they might view -ize as an American spelling. What is important is that you are consistent. For example, if you decide to go with realize, you should use the -ize ending for all verbs that can be spelled with either -ize or -ise. By doing so, you will minimize the risk of someone thinking you’ve made a mistake.

The -ise ending is actually newer than the -ize ending. In Britain and other countries, it became popular after 1875, when it began appearing in news articles. However, the -ise ending didn’t catch on in the United States or in British science periodicals and professional journals. For that reason, you will see both verb endings in British literature.

Oxford University Press, a British publisher, prefer to use the -ize ending for words that derive from the Greek suffix -izo. Doing so reflects the origins of verbs and nouns, such as realization, organization, and privatization. An -ise ending could erroneously suggest that the verbs derive from the French verbs réaliser, organiser, or privatiser. That’s not to say that Oxford style always condemns -ise endings. To illustrate, the -ise of televise doesn’t have a Greek origin, so that -ise ending is A-okay.

Examples
