Quick Answer: Analyse and analyze have the same meaning. Analyze is the standard spelling in American English, while analyse is preferred in British English and most other varieties of English.
The first time I submitted an article to an American client, my editor highlighted the word “analyse” and changed it to “analyze.” A few weeks later, I wrote for a UK-based website, and another editor changed it back to “analyse.” At first, I thought one editor had made a mistake. In reality, both were correct—they simply followed different English spelling conventions.
This is a common source of confusion for writers, students, bloggers, and English learners. Since the two words are pronounced the same and share the same meaning, it’s easy to wonder which spelling you should use.
The answer depends on the variety of English you’re writing in. Once you understand the regional spelling rules, choosing between analyse and analyze becomes simple.
In this guide, you’ll learn the difference, origin, grammar rules, regional preferences, real-world examples, common mistakes, and practical tips for using each spelling correctly.
Analyse or Analyze Quick Answer
Both analyse and analyze mean to examine something carefully in order to understand it or draw conclusions.
- ✅ Analyze = American English
- ✅ Analyse = British English, Australian English, and most Commonwealth English
Examples
- The scientist will analyze the results. (US English)
- The scientist will analyse the results. (UK English)
Both sentences are correct. The only difference is the regional spelling.
The Origin of Analyse and Analyze
The verb comes from the noun analysis, which traces its roots to the Ancient Greek word analysis, meaning a breaking up or examining of something. It entered English through Latin and French before becoming part of modern scientific and academic vocabulary.
According to Merriam-Webster, analyze became the preferred spelling in American English as spelling conventions evolved in the United States.
According to the Cambridge Dictionary, analyse is the standard spelling in British English.
This spelling difference follows a broader pattern in English. American English often uses -yze, while British English commonly uses -yse for certain verbs.
Examples include:
- analyze / analyse
- paralyze / paralyse
- catalyze / catalyse
However, not every verb follows this rule, so it’s best to check a dictionary when you’re unsure.
