American spelling avoids -ise endings in words like organize, realize and recognize.[35] British spelling mostly uses -ise, while -ize is also used (organise / organize, realise / realize, recognise / recognize):[35] the ratio between -ise and -ize stands at 3:2 in the British National Corpus.[36]
Worldwide, -ize endings prevail in scientific writing and are commonly used by many international organizations, such as the International Organization for Standardization and the World Health Organization.
