  J \J\ (j[=a]).
     J is the tenth letter of the English alphabet. It is a later
     variant form of the Roman letter I, used to express a
     consonantal sound, that is, originally, the sound of English
     y in yet. The forms J and I have, until a recent time, been
     classed together, and they have been used interchangeably.


     [1913 Webster]
  
     Note: In medical prescriptions j is still used in place of i
           at the end of a number, as a Roman numeral; as, vj,
           xij. J is etymologically most closely related to i, y,
           g; as in jot, iota; jest, gesture; join, jugular, yoke.
           See {I}. J is a compound vocal consonant, nearly
           equivalent in sound to dzh. It is exactly the same as g
           in gem. See Guide to Pronunciation, [sect][sect] 179,
           211, 239.
           [1913 Webster]

From WordNet (r) 2.0 [wn]:

  J
       n 1: a unit of electrical energy equal to the work done when a
            current of one ampere passes through a resistance of one
            ohm for one second [syn: {joule}, {watt second}]
       2: the 10th letter of the Roman alphabet

From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  J
       
          A derivative and redesign of {APL} with added features and
          control structures.  J is {purely functional} with {lexical
          scope} and more conventional control structures, plus several
          new concepts such as {function rank} and {function array}s.  J
          was designed and developed by Kennneth E. Iverson and Roger
          Hui .  J uses only the {ASCII}
          character set but has a spelling scheme that retains the
          advantages of {APL}'s special alphabet.  J is a conventional
          procedural programming language but can be used as a {purely
          functional} language.
