Analysing or Analyzing: Easy Spelling Guide

Analyzing is the American English spelling, while analysing is the British English spelling. Both have the same meaning.

I was checking a business report on my laptop when one word made me stop: analysing. The sentence looked fine, but the report was written for people in the US. I knew the American spelling uses a different letter.

This is why analysing or analyzing can be confusing. The two words sound the same and mean the same thing. The only real difference is the spelling used in different types of English.

If you write for people in the United States, use analyzing. If you write for people in the UK, use analysing.

Once you learn this simple rule, similar pairs become easier too. Words such as organizing/organising, realizing/realising, and recognizing/recognising follow a similar pattern.

Analyzing and analysing are two spellings of the same word.

• Analyzing is used in American English.

Which Spelling Should You Use?

The easiest way to choose is to think about your readers.

If you write for Americans

Use analyzing.

Use analysing.
