Difference Between “Analyse” and “Analyze”

Definition of Analyse

"Analyse" is the verb form used to describe the act of examining something in a detailed and systematic way, especially in order to understand it better or to draw conclusions from it. It is the spelling variation preferred in British English, along with other English varieties such as Australian, Canadian (to some extent), and New Zealand English.

Definition of Analyze

"Analyze" holds the identical definition as "analyse" but is the spelling favored in American English. This variation aligns with the American English tendency to use "-ize" endings for verbs that are spelled with "-ise" in British English.

Origin of Analyse and Analyze

Both “analyse” and “analyze” stem from the same etymological roots, tracing back to the Greek word “analysos,” which means “upbreaking” or “dissolving.” Over time, as English evolved and diversified across regions, spelling conventions diverged, leading to the development of two standard forms for many words, including “analyse/analyze.”


The pronunciation of both “analyse” and “analyze” is identical, /ˈæn.ə.laɪz/, highlighting that the difference between them is purely orthographic and regional.

The primary distinction between “analyse” and “analyze” lies in their usage within different variants of English. The choice between these forms does not affect the meaning of the term or its application but serves as an indicator of the writer’s or speaker’s adherence to either British or American English conventions.
