Shakespeare in Original Pronunciation
Shakespeare in Original Pronunciation, or simply Original Pronunciation (OP), is a movement dedicated to the examination and subsequent performance of Shakespeare's works in a loose reconstruction of Shakespeare's own Early Modern English phonology (accent), as devised by linguist David Crystal. While scholars in reality tremendously disagree on many specifics of Shakespeare's own accent, Crystal's Original Pronunciation is more adapted to theatrical performance onstage and the expectations of a modern audience.
