      String checkWord(String word)
      Reports warnings or errors associated with a supplied string. If the string is correct, or if it is empty or null, null is returned, otherwise some human-readable indication of what's wrong is returned.

      In general the warning does not need to quote the whole input string, though it can highlight particular parts of it if that's expected to be useful.

      Parameters:
      word - input text
      Returns:
      error message, or null for no error
