Abstract

Some studies classified a glide into a consonant, while others into a vowel or both. So did the case of a semi-vowel. Moreover, a glide is sometimes called as a semi-vowel. The number of English diphthong is not consistent along with different studies, which is closely related with a glide and a semi-vowel. In this regard, this paper aims to reveal what a glide is, what a semi-vowel is, what the relation between them is, what the number of a diphthong is in English, and what the phonetic and phonological characteristics of them are to answer the above questions. To do this, in Chapter 2 some studies on a glide and a semi-vowel are reviewed in terms of the choice of a particular term, either a glide or a semi-vowel. In Chapter 3 English glides are analysed in terms of phonetic aspect. In Chapter 4 phonological characteristics which are related to a glide, a semi-vowel and a diphthong are discussed. In Chapter 5 some selected studies on a diphthong are examined and discussed in terms of the phonological characteristics. It is concluded that each study chose a particular term and the number of English diphthongs in its own way, depending upon which being focused on among the phonological characteristics such as distinctive features, syllabicity, identification of phonemes, the phonemic structure of English, pattern congruity, simplicity, symmetry, naturalness of phonological processes and so on.
