Both words mean to decide what is most important and deal with it first. For example, you may need to prioritise your work before a busy day. An American writer may say they need to prioritize their work.
If you are writing an email, article, school assignment, business report, or website content, knowing which form to use can help your writing look polished and consistent.
This guide explains prioritise or prioritize, including their meaning, origin, British and American spelling, common mistakes, everyday examples, and simple tips for choosing the right form.
Prioritise or Prioritize – Quick Answer
Prioritise and prioritize are both correct spellings.
The difference is mainly based on the variety of English being used:
- Prioritise = British English
- Prioritize = American English
Both mean to decide what is most important and do it first.
Example 1: British English
We need to prioritise customer needs.
Example 2: American English
We need to prioritize customer needs.
Example 3: Everyday use
Please prioritize the most urgent tasks.
If you write for a British audience, use prioritise. If you write for an American audience, use prioritize.
The important thing is to stay consistent. Do not switch between the two forms without a reason.
The Origin of Prioritise or Prioritize
The word prioritize comes from the noun priority, which is related to the Latin word prior, meaning “earlier” or “first.”
The idea behind the word is simple: something with a higher priority should come before something with a lower priority.
The verb prioritize developed in modern English from the idea of giving something priority. The word became common in the 20th century, especially in business, management, education, and planning.
The spelling difference comes from a common British and American English pattern.
British English often uses -ise in words such as:
- prioritise
- organise
- recognise
- apologise
American English usually uses -ize:
- prioritize
- organize
- recognize
- apologize
However, -ize is also found in British English, especially in some formal styles and dictionaries. This means the difference is not always as strict as people think.
For everyday writing, prioritise is strongly associated with British English, while prioritize is strongly associated with American English.
British English vs American English Spelling
The main spelling difference is the ending:
British English → prioritise
American English → prioritize
| Version | Spelling | Region | Example Sentence |
|---|---|---|---|
| British English | prioritise | UK/Commonwealth | We must prioritise safety. |
| American English | prioritize | US | We must prioritize safety. |
| British-style spelling | prioritised | UK/Commonwealth | The team prioritised the project. |
| American-style spelling | prioritized | US | The team prioritized the project. |
The same pattern appears in related forms:
- prioritising / prioritizing
- prioritised / prioritized
- prioritisation / prioritization
There is an important detail: British English can also use -ize spellings. Some British dictionaries and style guides accept forms such as prioritize. Still, prioritise is very common in British writing.
Which Spelling Should You Use?
Your choice depends on your audience.
US audience
Use prioritize.
For example:
We need to prioritize customer service.
This is the standard and most familiar form for American readers.
UK/Commonwealth audience
Use prioritise if you are following the common British spelling style.
For example:
We need to prioritise customer service.
This form is also common in countries that generally follow British English conventions.
Global/SEO audience
For a global website, either form can be correct. Choose the spelling that matches your main audience.
If most of your readers are American, use prioritize.
If most readers are British or use British-style English, use prioritise.
For SEO, there is no need to force both spellings into every paragraph. You can naturally mention both once when explaining the difference and then use your chosen form consistently.
