History
Z, as you know, is the last letter in the alphabet out of our 26 letter alphabet. Historians believe that it came from a symbol used by the Semites, who once lived in Syria and Palestine. The Semites named it zayin and adopted an Egyptian Hieroglyphics for an arrow like object. Later, the Greeks make the symbol the sixth letter in the Greek alphabet, and called it zeta. They gave zeta the shape of the capitol Z we use today. The Romans used Z only when writing words borrowed from the Greeks, and moved the letter to the end of the alphabet. In Canada and Great Britain, Z is called zed. In some English dialects it is called izzard.
