New English

Great Vowel Shift – the change that happened in the 14^th – 16^th c.and affected all long monophthongs + diphthong [au]. As a result these vowels were:

· diphthongized;

· narrowed (became more closed);

· both diphthongized and narrowed.

This shift was not followed by spelling changes, i.e. it was not reflected in written form. Thus the Great Vowel Shift explains many modern rules of reading.
