Usage notesEdit
  • Many English verbs end in the suffix /aɪz/. Historically, this has been spelled -ize on words originating from Greek (for example baptize, Hellenize), while -ise has been used, especially in -vise, -tise, -cise, and -prise, on words that came from French or Latin roots (for example surprise, supervise). In the 19th century, it became common in the United Kingdom (due to French influence), and then also in Ireland, India, Australia, and New Zealand, to use -ise also on words that had historically been spelled -ize (hence baptise, Hellenise). However, the influential Oxford University Press and its Oxford English Dictionary continue to use the spelling -ize on Greek words, and -ize always been the spelling used in the United States and Canada on such words.
