He made up his own words! Broke all the #@!ing rules! Of course other writers at the time thought he was crap. Mucho food for thought here, especially if you consider yourself a language purist:
13 Words Invented by Shakespeare
from Huffington Post
(which should credit the writer but we can’t find it)
Like Precalculus and Newton’s laws, Shakespeare’s plays are among the most groaned-about high school topics, begetting the complaint: “When will I ever need to know about this in real life?” Turns out, pretty often. Shakespeare can be credited for the invention of thousands of words that are now an everyday part of the English language (including, but not limited to, “eyeball,” “fashionable,” and “manager.”)
In addition to his being a particularly clever wordsmith, Shakespeare’s word invention can be credited to the fact that the English language as a whole was in a major state of flux during the time that he was writing. Colonization and wars meant that English speakers were borrowing more and more words from other languages.
