“Analyze” or “Analyse” are words that often cause confusion, especially for English learners or writers who work with international audiences.
“Analyze” and “analyse” have the same meaning, but their usage depends on location. “Analyze” is the preferred spelling in American English, while “analyse” is commonly used in British English. Understanding this distinction ensures better communication and localization in professional and academic writing.
While these two spellings refer to the same verb meaning “to examine or study something in detail,” the difference comes down to regional variations in English, particularly between American and British English.

When Should You Use “Analyze” or “Analyse”?
Writing for an American Audience
Email Example:
Subject: Analyzing Quarterly Sales Data
Hi Mia,
I’ve spent the past week analyzing the sales data for the last quarter, and I’ve noticed some interesting trends. The customer base seems to be shifting toward a younger demographic, and online sales have spiked by 20%. I believe we need to shift our marketing strategies to focus more on digital platforms.
Let’s schedule a meeting to go over the analysis and discuss potential action plans.
Best regards,
Hannah
In this email, Hannah is using “analyze” since the context is an American English setting. The focus is on examining and interpreting the sales data.
Writing for a British Audience
Memo Example:
Subject: Analysing Marketing Campaign Results
Dear Team,
After carefully analysing the data from our recent marketing campaign, I’ve found that customer engagement was significantly higher in regions where we targeted social media influencers. However, our traditional methods did not perform as well as expected.
I recommend a follow-up meeting to discuss changes to our strategy based on these findings. Please review the detailed report and share your thoughts.
Regards,
Hannah
In this memo, the British spelling “analyse” is used because the audience is based in the UK. The focus is the same — detailed examination of marketing results.
Historical Context and Evolution of Spelling
The difference between “analyze” and “analyse” dates back to the evolution of American and British English spellings. British English tends to preserve older spelling rules derived from Greek and Latin. The -ise ending in words like analyse comes from the Greek suffix -izein, which was later adapted by Latin into -izare.
In contrast, American English simplified many spellings, favoring the -ize form over -ise in verbs. This change aimed to make spelling more phonetic and consistent with how words are pronounced in American English. As a result, we have distinctions like “analyze” in the U.S. and “analyse” in the UK.
Academic Context
Research Paper Example:
In academic settings, it’s critical to choose the correct spelling based on the country of publication.

In this study, we seek to analyze the social behaviors of children in different educational environments. By collecting qualitative data through interviews and surveys, we aim to identify patterns and variables that influence learning outcomes.
British English (Analyse):
This research aims to analyse the effects of climate change on biodiversity in coastal ecosystems. A detailed examination of data collected over the past 20 years will provide insights into species adaptation and habitat changes.
Additional Usage:
- Data Analysis: No matter the spelling, data analysis refers to the process of collecting, organizing, and interpreting data to draw conclusions.
- Analysis (noun): Both analyze and analyse share the same noun form, analysis.
Quick Tip to Remember the Difference
If you’re unsure which spelling to use, here’s a simple guideline:
