English language in Europe following the Norman Conquest in 1066, the Anglo-Norman language was the language of administration and few Kings of England spoke English. A large number of French words were assimilated into Old English, which lost most of its inflections, the result being Middle English. Around the year 1500, the Great Vowel Shift marked the transformation of Middle English into Modern English. The most famous surviving work from Old English is "Beowulf", and from Middle English is Geoffrey Chaucer's "The Canterbury Tales". The rise of Modern English began around the fifteenth century, with Early Modern English reaching its literary pinnacle at the
Proto-Germanic language of Proto-Indo-European and its gradual divergence into a separate language. As it is probable that the development of this sound shift spanned a considerable time (several centuries), Proto-Germanic cannot adequately be reconstructed as a simple node in a tree model but rather represents a phase of development that may span close to a thousand years. The end of the Common Germanic period is reached with the beginning of the Migration Period in the fourth century. The alternative term "Germanic parent language" may be used to include a larger scope of linguistic developments, spanning the Nordic Bronze Age and Pre-Roman Iron
