Zed is the name of the letter Z. The pronunciation zed is more commonly used in Canadian English than zee. English speakers in other Commonwealth countries also prefer the pronunciation zed. As zed is the British pronunciation and zee is chiefly American, zed represents one of the rare occasions in which most Canadians prefer the British to the American pronunciation. Use of zee is often stigmatized among Canadian English speakers, which is likely the reason why zee has not taken root as quickly as other influences from American English.
