Crystal has also authored many books on linguistics covering topics such as orthography, phonetics, phonology, and language evolution. He also worked on two encyclopaedias for the Cambridge University Press, The Cambridge Encyclopedia of Language and The Cambridge Encyclopedia of the English Language.
As Crystal is an expert on language, linguistics, Shakespearean English, and the evolution of the English language, he worked on productions of Shakespeare at the reconstructed Globe Theatre in Southwark, London.
Currently, Crystal works from his home in Holyhead and is working on a new book, Wordsmiths and Warriors: the English-language Tourist's guide to Britain, with his wife Hilary, which is due for release September of this year. We can't wait!
Happy Birthday David!
