Why is the alphabet A to Z?
The Greeks started to use an alphabetic system of their own around the 8th century BC, adding vowels and the letter X. It's the Romans who turned it into the alphabet as we use it today. As RD.com points out, it was the Romans who took the letters Y and Z from the front of the alphabet, and tacked them onto the end.18 Aug 2017
