Final answer:
The Shakespearean character that is NOT a common noun is 4. Prince.
Step-by-step explanation:
The Shakespearean character that is NOT a common noun is 4. Prince.
In Shakespeare's plays, many characters have names that can also be common nouns, such as Romeo, Macbeth, and Othello. However, the term 'Prince' refers to a title or a position of power and is not a common noun in the same sense.
