Лекция: Diphthongs and their classification

A diphthong/'dIfTPN/ is a movement or glide from one vowel to another. A vowel which remains constant and does not glide is called a pure vowel. Diphthongs are equivalent to the long simple vowels in their length. The first part of the diphthong is much longer and stronger than the second part. As the glide towards the second vowel happens, the loudness of the sound becomes less. As a result, the second element is shorter and quieter.

Diphthongs can be divided into two groups (see Figure 4):
