Personalise and personalize are both correct spellings, but the right choice depends on the type of English you are using. Personalize is the standard spelling in American English, while personalise is the usual spelling in British English and is also common in other varieties of English that follow British spelling.
People often search for personalise or personalize because the two forms have the same meaning and pronunciation. The only clear difference is the spelling of the ending: -ise or -ize. This can be confusing when writing for an international audience, especially in schoolwork, business documents, websites, or professional emails.
Both forms mean to make something suitable for a particular person or to make something more personal. For example, you can personalise a message for a UK audience or personalize a message for a US audience.
The choice is mainly based on regional spelling conventions, not meaning. In this guide, you will learn the difference between the two forms, their origin, regional usage, common mistakes, and practical examples.

What Does Personalise or Personalize Mean?
Personalise and personalize are verbs.
They mean to change something so it is more suitable for a particular person or to give something a personal character.
Cambridge defines personalization as changing or adding to something so that it belongs to or comes from a particular person. It also uses the word for making something suitable for an individual’s needs.
Personalise or Personalize an Object
You can use the verb when you change an object to make it personal.

American English:

Personalise or Personalize a Service
The word is also common in business.

Personalize Can Have Another Meaning
The verb can also mean to make an abstract subject more relatable by using real people or personal examples.
For example:
The writer personalized the story by describing real experiences.
So, the word can relate to customization, individual needs, or personal examples, depending on the context.
The Origin of Personalise or Personalize
The word personalize comes from the adjective personal combined with the verb-forming suffix -ize. Historical records date the verb to around 1747. The form personalise is also recorded from the same period.
The word personal itself has a much older history. It came into English through Old French from Late Latin personalis, meaning relating to a person.
The spelling difference developed from a broader pattern in English:
-ize and -ise
Both endings can appear in English verbs. British English has traditionally used -ise widely, while American English generally prefers -ize.
This creates pairs such as:
- personalise / personalize
- organise / organize
- realise / realize
- recognise / recognize
- apologise / apologize
The meaning does not normally change because of the ending.
Why Does British English Use -ise?
British English commonly uses -ise in everyday publishing and general writing.
At the same time, -ize is also used by some British publishers and style systems. The Oxford style tradition, for example, has historically favored -ize in many words of this type.
Therefore, it is better to say:
Personalise is the usual British form, while personalize is the standard American form.
The difference is mainly one of spelling convention and style preference.
British English vs American English
The clearest regional difference is the ending.
| Meaning | British English | American English | Example |

Is -ize Wrong in British English?
