Well, Shakespeare had knowledge of seven different languages, and had an estimated vocabulary of about 24,000 words; a truly staggering amount. This background allowed for him to invent new words for the English language-- over 1,700 to be exact-- and also to flesh out our language in more ways than one. In many ways, these words are his most underrated works. Below are some of the most popular (I copied and pasted the word list from William Shakespeare: His Influence in the English Language):
