Diphthong

  • american english pronunciation of no highway cowboys, showing five diphthongs: ɔɪ/

    a diphthong (ŋ/ dif-thong or ŋ/ dip-thong;[1] from greek: δίφθονγος, diphthongos, literally "double sound" or "double tone"), also known as a gliding vowel, is a combination of two adjacent vowel sounds within the same syllable.[2] 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 cowboys z/ has five distinct diphthongs, one in every syllable.

    diphthongs contrast with monophthongs, where the tongue or other speech organs do not move and the syllable contains only a single vowel sound. for instance, in english, the word ah is spoken as a monophthong (ɑː/), while the word ow is spoken as a diphthong in most varieties (/). where two adjacent vowel sounds occur in different syllables—for example, in the english word re-elect—the result is described as hiatus, not as a diphthong. (the english word hiatus s/ is itself an example of both hiatus and diphthongs.)

    diphthongs often form when separate vowels are run together in rapid speech during a conversation. however, there are also unitary diphthongs, as in the english examples above, which are heard by listeners as single-vowel sounds (phonemes).[3]
