13 grammar, but also about the pronunciation. Language is a way to communicate

Yallop and Clark 1990, p. 90 states, diphthongs seem to be another instance of two phonetic segments functioning as one. They are, in a sense, two
vowels forming a single entity and are analogous to affricates or prenasalized plosives in that they are generally regarded as single but complex segments Clark

The term diphthong is reserved for a glide between two vowel qualities, neither of which dominates. The categorized of glide is based on the major of
auditory distinction that divide the continuum of articulatory timing. According to Javed and Ahmad 2014, the combination of two vowel
sounds rapidly gliding from one sound to another is called a diphthong. There are eight 3 centering and 5 closing diphthongs in the British English language sound
system. Three sounds such as ɪə hear, eə wear, and ʊə tour are called centering diphthongs ending at ə schwa sound.
Three sounds ending at ɪ such as eɪ day, ɑɪ my, ɔɪ boy are known as closing diphthongs and lastly two sounds that culminate at ʊ such as əʊ go,
aʊ how are also called closing diphthongs Javad and Ahmad, 2014.
One can also classify diphthongs into rising diphthongs, narrow diphthongs, and wide diphthongs. A rising diphthongs is a diphthong in which the end part has
14 greater prominence than the beginning part. A narrow diphthongs is in which the
movement of the tongue is relatively small, for examples the diphthongs ei and ou. A wide diphthong is in which the movement of the tongue is relatively great,
for examples ai and au.
