A diphthong is a combination of two vowel sounds that are pronounced together as a single sound. It occurs when a speaker transitions from one vowel sound to another within a single syllable. To understand what a diphthong is, you can follow these steps:

1. Start by listening to the word or sound you're curious about. In this case, let's take the word "coin" as an example.

2. Pay attention to how the vowel sound changes within the word. In "coin," you might notice that the sound starts with something similar to the "oh" vowel sound and transitions to an "ee" sound.

3. By blending the two vowel sounds together, you can hear the complete pronunciation of the word. In this case, the diphthong in "coin" is formed by the "oi" combination.

Remember, diphthongs can differ across languages, dialects, and accents. However, this method of focusing on the transition of two vowel sounds within a single syllable will help you identify diphthongs in most cases.
