A good alternative to using a set would be to use a dictionary. The collections module contains a class called Counter which is specialized dictionary for counting the number of times each of its keys are seen. Using it you could do something like this:

from collections import Counter

wordlist = ['Arise', 'But', 'It', 'Juliet', 'Who', 'already', 'and', 'and',
            'and', 'breaks', 'east', 'envious', 'fair', 'grief', 'is', 'is',
            'is', 'kill', 'light', 'moon', 'pale', 'sick', 'soft', 'sun', 'sun',
            'the', 'the', 'the', 'through', 'what', 'window', 'with', 'yonder']

newlist = sorted(Counter(wordlist), 
                 key=lambda w: w.lower())  # case insensitive sort
print(newlist)

Output:

['already', 'and', 'Arise', 'breaks', 'But', 'east', 'envious', 'fair',
 'grief', 'is', 'It', 'Juliet', 'kill', 'light', 'moon', 'pale', 'sick',
 'soft', 'sun', 'the', 'through', 'what', 'Who', 'window', 'with', 'yonder']
