What are Diphthongs?
- A diphthong is a complex vowel sound that begins with one vowel sound and glides into another within the same syllable.
- Diphthongs occur when the tongue moves from one vowel position to another within the same sound.
Examples of Common English Diphthongs
- /aɪ/ as in my, fly
- /eɪ/ as in say, day
- /ɔɪ/ as in boy, toy
- /aʊ/ as in how, now
- /əʊ/ as in go, no
- /ɪə/ as in ear, fear
- /eə/ as in air, share
Diphthongs vs. Monophthongs
- Monophthongs are single, pure vowel sounds like /æ/ in cat and /ɪ/ in sit.
- Diphthongs are combinations of two vowel sounds within one syllable, as seen in coin (/ɔɪ/).
How to Pronounce Diphthongs
- Start with the first vowel sound, then glide into the second one. For example, in the diphthong /aɪ/ (as in my), begin with the /a/ sound and smoothly glide to the /ɪ/ sound.
