  X
       
          1.  Used in various speech and writing contexts
          (also in lowercase) in roughly its algebraic sense of "unknown
          within a set defined by context" (compare N).  Thus, the
          abbreviation 680x0 stands for 68000, 68010, 68020, 68030 or
          68040, and 80x86 stands for Intel 80186, Intel 80286,
          Intel 80386 or Intel 80486.  A Unix hacker might write
          these as 680[0-4]0 and 80[1-4]86 or 680?0 and 80?86
          respectively; see glob.
       
          2.  An alternative name for the X Window System.
       
          3.  A suffix for the speed of a CD-ROM drive
          relative to standard music CDs (1x).  32x is common in
          September 1999.

  X \X\ ([e^]ks).
     X, the twenty-fourth letter of the English alphabet, has
     three sounds; a compound nonvocal sound (that of ks), as in
     wax; a compound vocal sound (that of gz), as in example; and,
     at the beginning of a word, a simple vocal sound (that of z),
     as in xanthic. See Guide to Pronunciation, [sect][sect] 217,
     270, 271.
     [1913 Webster]
  
     Note: The form and value of X are from the Latin X, which is
           from the Greek [Chi], which in some Greek alphabets had
           the value of ks, though in the one now in common use it
           represents an aspirated sound of k.
           [1913 Webster]
