A diphthong is a single-syllable vowel sound in which the beginning of the sound is different from the end sound—that is, the sound glides from one vowel sound to another. For this reason, diphthongs are often referred to as gliding vowels.
There are eight vowel sounds in American English that are generally agreed upon as being diphthongs.
diph·thong(dĭf′thông′, -thŏng′, dĭp′-)
A complex speech sound or glide that begins with one vowel and gradually changes to another vowel within the same syllable, as (oi) in boil or (ī) in fine.
[Middle English diptonge, from Old French diptongue, from Late Latin diphthongus, from Greek diphthongos : di-, two; see di-1 + phthongos, sound.]
