      max_word_size: Maximum size of the words to consider. Words larger
      than this will be kept unchanged.
  
      cutoff: The cut-off point. For each word, there could be many
      possibilities. By default 3 of these possibilities are considered
      for each word. This number can be changed by this argument.
