Thank you for this introduction which, however short it is, raises some important questions. For example, concerning the latter point of the video: Shakespeare's lexicon contains 20-25 thousands of words, 3200 of which he introduced to the English language. In that perspective, the fact that Shakspere's (as in his signatures) daughter Judith was illiterate at the age of 27 seems like a blunder of his, doesn't it?
