Thanks for the code Rollis13! Unfortunately, it doesn't exactly do what I want: it does delete the words with less than 3 characters when it considers the most repeated words, but not when it's the most repeated 2-3-4 consecutive words.

For example, if a quote is like this:

''I would like to have bread.''

I want it to cut it to this:

'Would like have bread.''

And do this for all the text, and then tell me what are the most repeated consecutive words. Hope it's more clear!

And when you say inaccuracies, which one do you see?
