Usage notesEdit

  • The suffix -ize has historically been used on words originating from Greek. -ise was used, especially as -vise, -tise, -cise, and -prise, on words that come from various roots (usually via French). In the 19th century, it became common in the United Kingdom (due to French influence) to use -ise also on words that had historically been spelled -ize. -ise is also common in Ireland, Australia, and New Zealand. -ize remains, however, the spelling used by the influential Oxford University Press; it has also always been the spelling used in the United States and Canada.
