Diphthong

A diphthong (/ˈdɪfθɒŋ/ DIF-thong or /ˈdɪpθɒŋ/ DIP-thong; from Greek: δίφθογγος, diphthongos, literally "double sound" or "double tone"; from δίς "twice" and φθόγγος "sound"), also known as a gliding vowel, is a combination of two adjacent vowel sounds within the same syllable. Technically, a diphthong is a vowel with two different targets: that is, the tongue (and/or other parts of the speech apparatus) moves during the pronunciation of the vowel. In most varieties of English, the phrase no highway cowboy /ˌnoʊ ˈhaɪweɪ ˈkaʊbɔɪ/ has five distinct diphthongs, one in every syllable.
