The reason hun is because Shakespeare uses an early form of the English language. There are a few differences between today's English and Shakespeare's Early Modern English. He uses words such as thee, thy, lord, thou, art, etc which is complicated for us to understand. Also, many of Shakespeare's plays were written in iambic pentameter which makes his writings much more difficult to interpret. Another thing is that he invented new words in his writings, over 1,000 words he invented.
