Why do we say Z instead of Zed?
The question should be asked the other way around: “Why do US Americans say “zee” instead of “zed” for the letter “Z”? The word for the letter is ultimately from Greek “zeta” which passed into Latin as “zeta”. English took the word from Middle French “zede”.
Why is the letter Z replaced by S?
Early English—it should be noted—did not have a Z but used S for both voiced and unvoiced sibilants. Words in English that originated as loanwords from French and Latin are more likely to be spelled with a Z than an S, such as blazon or buzzard.
Why is Z so rare?
It is also thought due to rhotacism, Z became a trilled R sound, /r/. Whatever the case may be, Appius Claudius' distaste for the letter Z is today credited as the reason for its removal.
Is Z the last letter in the Greek alphabet?
Explanation: Despite the first letter of its name, Zeta is NOT the final Greek letter, but the sixth.
