Recognize vs recognise

Recognize means to remember, acknowledge truth or legal authority, or to realize something.

British English lists an alternate spelling as recognise, but the main entry is recognize. North Americans (yes, that includes Canada) prefer the ize spelling, and this is accepted everywhere. However, outside North America some prefer the ise spelling and it is not incorrect. This spelling change goes across all derivatives including: recognizability, recognisability, recognizable, recognisable, recognizeably, recognisably, recognizer, and recogniser.

The ize/ise change is based in English being influenced by French, and every other language. The Greek words changed to Latin, which used a z, but the French spelled it with an s. Purists in England promote the original ize while others stick with convention, ise.
