Shakespeare's Words: A Glossary And Language Companion by Ben Crystal
This is a book for anyone who wants to understand all the nuances of Shakespeare's language: David Crystal and his actor son, Ben, have collected 4000 words from Shakespeare's lexicon which are frequently misunderstood by, or incomprehensible to, the modern reader. The words are glossed and there is a quotation illustrating the word in context. They have also collected into panels words of particular kinds (Shakespeare's bawdy for example). The book includes a unique series of diagrammatical representations of the relationships between characters and places for each play.
