1. A word information storage and retrieval apparatus comprising:

  • a plurality of character keys for entering first word information representing a desired word in original form;

    search means responsive to said plurality of character keys for searching second word information representing said desired word in a variant form, said search means including;

    an original form memory for containing original forms of a plurality of words;

    at least one variant form memory for containing variant forms corresponding to said plurality of words;

    a counter for producing an incremental count upon the initiation of searching;

    a coincidence detector for sequentially comparing said desired word with the original forms of said plurality of words stored in said original form memory;

    said coincidence detector comparing said desired word with the original form of a new one of said plurality of words with each increment of said counter, a detected coincidence stopping the incremental count of said counter to thereby allow said counter to produce a signal representative of the original form of the word corresponding to said desired word;

    said signal generated by said counter being used to address and recall the variant form of said desired word from one of said at least one variant form memories; and

    a display responsive to said variant form of said desired word for indicating said second word information.
