The Origin of Analyzed vs Analysed
The word analyze / analyse comes from the Greek analusis, meaning to break up or to loosen. It entered English in the 17th century and was used to describe studying something in detail to understand it better.
The spelling difference developed later due to American spelling reforms in the 19th century. Noah Webster, an American lexicographer, advocated for simplified and standardized spellings to make English easier to learn. That is why American English prefers -ize endings, including analyze → analyzed, while British English traditionally keeps the -ise ending: analyse → analysed.
