History of Z Day
The letter Z is the 26th and final letter of the modern English alphabet. It has different pronunciations in the different English dialects. In British English, spoken in the U.K. and Australia, it’s pronounced /zed/. In American English, it’s pronounced /zee/. In Hong Kong English and Cantonese, Z is pronounced /izzard/.
The seventh letter of the Hebrew alphabet is called ‘zayin’ and is used to represent the sounds /z/ and /dz/. ‘Zayin’ in Semitic means ‘weapon’ or ‘sword.’
The ancient Greeks copied their form of Z from the Phoenician ‘zayin,’ and it was called zeta. It had different pronunciations in the different Greek dialects. In the dialect spoken in Athens and Northwest Greece, it was pronounced /dz/, but later changed to represent /zd/ and /dz/ in the 4th century B.C. The Elean and Cretan dialects pronounced it as the English voiced and voiceless /th/.
The Latin version of Z was adopted from Etruscan Z and pronounced as /ts/. However, around 300 B.C., the sound /z/ was changed to /r/due to a process called rhotacism. It was then dropped from the Latin alphabet by the Roman Censor Appius Claudius Caecus. Its place in the alphabet was replaced with the new letter G. Later in the 1st century, Z was reintroduced to the Latin alphabet, along with the letter Y.
Before Z became the final letter of the modern English alphabet, there was a twenty-seventh letter, &. The symbol “&,” pronounced as “and,” was recited in Latin as “per se.” From being recited as “X, Y, Z, and per se and,” it became “X, Y, Z, ampersand.”
