One of the best diphthong examples is the word “oil.” Here, we have two vowels working side by side and, together, they create a sound different than anything “O” or “I” alone can produce.

This is the example ;

A diphthong is a sound formed by combining two vowels in a single syllable. The sound begins as one vowel sound and moves towards another. The two most common diphthongs in the English language are the letter combination “oy”/“oi”, as in “boy” or “coin”, and “ow”/ “ou”, as in “cloud” or “cow”.
