1. A system for checking a spelling of an input English word comprising:

  • an input means for inputting an English word;

    an electronic dictionary memory for storing English words in four groups, wherein every word in each group can have a common suffix and is stored without the suffix, and the four groups include a first group of words that can have a suffix "s";

    a second group of words that can have a suffix "s", "ing", or "ed";

    a third group of words that can have a suffix "ly"; and

    a fourth group of other words;

    a search means for searching whether or not an input word exists in the dictionary memory;

    a suffix judgement means for judging whether or not an input word has one of the suffixes by which words in the dictionary memory are classified and, if the input word has one of the suffixes, for eliminating the suffix of the input word and for cooperating with the search means to search for word data in the dictionary memory coincident with a de-suffixed form of the input word within the group corresponding to the suffix,wherein if the input word does not have one of the suffixes by which the words in the dictionary are classified, or if word data coincident with the de-suffixed form of the input word does not exist within the group corresponding to the suffix, the search means searches for word data in the dictionary memory coincident with the input word; and

    an output means for displaying the input word and, if word data coincident with the input word or de-suffixed form of the input word does not exist in the dictionary memory, for displaying the input word distinctively.
