This article solves that confusion clearly and simply. You’ll get a quick answer, learn where both spellings come from, see how British and American English differ, and understand which spelling is best for your audience.

Minimise or Minimize – Quick Answer

Both spellings are correct.

Minimise is British English.
Minimize is American English.

Examples:

We need to minimise costs this year. (UK)
We need to minimize costs this year. (US)

The meaning is exactly the same: to make something as small or as low as possible.

The Origin of Minimise or Minimize

The word comes from the Latin word minimus, meaning smallest. When English adopted this word, different spelling traditions developed over time.

In British English, many verbs ending in -ize changed to -ise, influenced by French spelling patterns. In American English, spelling reformers—most famously Noah Webster—pushed for simpler and more consistent spellings. As a result, American English kept -ize, while British English often uses -ise.

That’s why we have pairs like:

minimise / minimize
organise / organize
realise / realize

The spelling difference exists because English evolved differently on each side of the Atlantic.
