What does the name Kazi mean?
Kazi is a spelling of Casey, pronounced the same way, so it shares Casey's meaning and origin.
Casey is the English form of the Irish surname Ó Cathasaigh, "descendant of Cathasach", a personal name Wiktionary glosses as "watchful, vigilant". Woulfe's 1923 index lists Casey under the Gaelic surnames it anglicizes. Woulfe also lists a "son of" form, Mac Cathasaigh, which gave MacCasey and sometimes plain Casey. As a first name Casey is used for both boys and girls.
