The Origin of Organised / Organized

The word organize comes from the Greek word organon, meaning “tool” or “instrument,” and the Latin organizare, meaning “to form into a system.”

Spelling differences appear because British English often favors -ise, while American English prefers -ize. Both forms entered English through French influence in the 15th–16th centuries, but over time, the US standardized -ize endings.
