Index is used to keep track of which character is being iterated over in the word to spell checked. It is also used to verify that the word being spell-checked is a word meeting the standard of, a certain length. i.e not longer than the longest word in the English Language. Index is used wherever we are dealing with words to be spell-checked, checking if a word is the correct length and iterating over the alphabets in the word to be spell-checked.
