  • Interesting fact: The name for Oz in "The Wizard of Oz" was thought up when the creator, Frank Baum, looked at his filing cabinet and saw A-N, and O-Z, hence "Oz."
    • Z zē; in England commonly, and in America sometimes, zĕd; formerly, also, ĭz"zĕrd 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, §§ 273, 274.

  • Interesting fact: Frank Baum named "Oz" after a file cabinet in his office. One cabinet was labeled "A to N," and the second was labeled "O to Z."
    • n z In astronomy, an abbreviation of Zonæ Cordobenses, Gould's Cordova Zones. See C. Z.

    • z The twenty-sixth character in the English alphabet, and the last, as in that of the later Romans. In the Phenician system, from which ours comes through the Latin and Greek, it was the seventh sign. The comparison of ancient forms, including the Egyptian as perhaps the original (compare A), is as follows: The same character has a corresponding place as zeta in the Greek series, and went over in that place to the Italian alphabets; but, about the third century b. c., it was dropped out by the Romans as not needed, and the newly devised G (see G) was put in its place. Then finally, some two centuries later, it was taken back (together with or soon after Y: see Y) to express in borrowed Greek words the peculiar double sound (ds or sd) which it had won in Greek usage, and so appeared anew in its old company, but with greatly altered position. It was not used in the oldest English, but came gradually in out of the French in the fifteenth century and later. With us, as in French, it has lost its value of a compound consonant, and expresses the sonant or voiced sibilant sound corresponding to s as surd or breathed sibilant. The proper z-sound is also, and even much oftener, written by s, as in roses, and in a few words (as possess, dissolve) by double s, and yet more rarely (for example, sacrifice) by c. The sound is a common one in our English pronunciation—not much less than 3 per cent. (the surd s being 4⅔ per cent.). As initial, the character z is written mostly in words of Greek origin, but as final (almost always with silent e added) it is found in many Germanic words, as freeze, graze. It occurs sometimes double, as in buzz, buzzard. The corresponding sonant to our other sibilant (written in this work with zh, after the example of sh) is spelled with either s or z, as in pleasure, azure. It is the rarest of our consonant sounds, counting for only a fiftieth of 1 per cent. of our utterance. In certain Scotch words and names, as capercailzie, Dalziel, z is written for the y-sound. In the United States the character is generally called zee; in England, generally zed (from zeta); izzard (which see) is an old name for it.
    • z As a symbol, in mathematics:
    • z [lowercase] In algebra, the third variable or unknown quantity.
    • z [lowercase] In analytical geometry, one of the system of point-coördinates in space.
    • z In mechanics, the component of a force in the direction of the axis of z.

  • Interesting fact: Frank Baum, looked at his filing cabinet and saw A-N, and O-Z, hence "Oz."
    • Z the twenty-sixth and last letter in our alphabet, is derived through the Greek zeta, from zayin, the seventh Semitic letter—its sound a voiced sibilant, either a voiced s as in 'zeal,' or a voiced sh as in 'azure.'—The cedilla (ç) is a 'little zed,' as is implied by the Italian name zediglia, from zeticula.
