Z \Z\ (z[=e]; in England commonly, and in America sometimes,
   z[e^]d; formerly, also, [i^]z"z[e^]rd)
   Z, the twenty-sixth and last letter of the English alphabet,
   is a vocal consonant. It is taken from the Latin letter Z,
   which came from the Greek alphabet, this having it from a
   Semitic source. The ultimate origin is probably Egyptian.
   Etymologically, it is most closely related to s, y, and j; as
   in glass, glaze; E. yoke, Gr. ?, L. yugum; E. zealous,
   jealous. See Guide to Pronunciation, [sect][sect] 273, 274.
