There are many spelling differences between American and British English. In some cases, the same word will be spelled one way in American English and another way in British English. There are times when this inconsistency is very confusing.
Realise and realize are two variants of the same word. One spelling is more common in American English, while the other is more common in British English.
Since both of these forms are accepted somewhere in the world, neither is technically wrong. Still, any time you are writing, you should consider your intended audience. This principle extends to spelling differences, as well.
You will want to use British spellings when writing for a primarily British audience, and American spellings if you are writing for a predominantly American audience.
What is the Difference Between Realise and Realize?
In this article, I will compare realise vs. realize. I will use each spelling in a sentence, and then I’ll show you a helpful trick to use when you can’t decide whether to use realise or realize in your own writing.
When to Use Realize
What does realize mean? Realize is a verb that means to become aware of something or to bring something into being. The ize spelling is the sole spelling in American English and is also common in British English.
Realize is a regular verb and can be conjugated into various tenses by adding -d, -s, and -ing.
- In the meeting, I realized that I had forgotten to brush my teeth this morning.
- Do you realize that you have the most beautiful face?
- Karen sold her shares of the electric company at $44.50, for a total realized gain of over six million dollars.

When to Use Realise
What does realise mean? Realise is a British variant spelling of this verb. It can be used in any of the same contexts as realize.

While realise is comparatively more common in British English than American English, digital data on British books show that realize has been the predominant spelling in British English for almost 10 years.
These graphs tells a similar story of many British, American –ise, -ize spelling differences. Namely, British writers use both spelling with some frequency, while American writers have universally standardized around the -ize spellings.
Books like Folwer’s state that the Oxford University Press prefers ize spellings, while Cambridge University Press prefers ise spellings, which shows that both are used in British English.
Unless your workplace has a strong preference, however, it’s best to default to the ize spelling since the most people tend to use this spelling.
