係 我都係大個先知
其實係因為Oxford Dictionary用-ize
但係其實英國人普遍係用-ise
University of Oxford Style Guide
Spelling
General guidelines
Use suffix -ise/-yse/-isation not -ize/-yze/-ization. Note that this is
different from OUP’s choice, because OUP prefers to reflect the Greek roots
of some such words. We prefer ‘-ise’ as it is more common in British usage
and requires fewer exceptions.
