Recognize or Recognise Quick Answer

Recognize and recognise are both correct spellings.

The main difference is regional:

• Recognize → American English
• Recognise → British English

Both words have the same meaning: to identify someone or something, or to accept or acknowledge something.

Examples

American English:

I did not recognize him at first.

British English:

I did not recognise him at first.

Another example:

American: She recognized the importance of education.

British: She recognised the importance of education.

There is no difference in meaning or pronunciation. The main difference is the spelling convention.

The Origin of Recognize or Recognise

The word recognize comes from Latin roots. It is related to the Latin word recognoscere, which means “to know again,” “to identify,” or “to acknowledge.”

The word entered English through French and developed into the modern form recognize.

Over time, English developed different spelling traditions. One important difference is the use of -ize and -ise endings.

American English generally prefers -ize, while British English commonly uses -ise.

For example:

• American: organize
• British: organise
• American: realize
• British: realise
• American: apologize
• British: apologise
• American: recognize
• British: recognise

This is why both recognize and recognise exist today.

It is important to remember that British English can also use -ize spellings in some styles. However, -ise is very common in standard British writing.

British English vs American English Spelling

The main spelling difference is the ending.

American English usually uses -ize.

British English commonly uses -ise.

The company recognised her hard work.

Both sentences are correct.

The same rule applies to the past tense.

• American: recognized

• American: recognizing

Which Spelling Should You Use?

The best choice depends on your audience.

For American Readers

Use recognize if your content is written in American English.

For example:

We recognize the value of customer feedback.

If your website targets readers in the United States, keeping American spelling throughout your content is a good approach.

For British Readers

Use recognise when following the common British English spelling style.

For example:

We recognise the value of customer feedback.

This spelling is also commonly seen in British-style writing.

For Commonwealth Countries

Many countries use British English spelling conventions. In these cases, recognise is often the preferred form.

However, spelling preferences can vary by country, organization, publisher, and style guide.

For a Global Audience

If your website has readers from different countries, choose one spelling system and use it consistently.

For example, if your website mainly follows American English, use:

• recognize
• recognized
• recognizing

If it follows British English, use:

• recognise
• recognised
• recognising

Consistency is more important than choosing one form as universally correct.

Mistake 1: Thinking Recognise Is Wrong

Some American English users may think recognise is misspelled.
