What are vowel diagraphs?

Vowel digraphs are pairs of vowels that together make a single sound. Some common vowel digraphs include:

- ai (as in rain)
- ea (as in eat)
- ee (as in see)
- oa (as in boat)
- ie (as in pie)
- ue (as in blue)

Vowel diagraphs are two vowels that are combined to represent a single sound. They are different from diphthongs, which are two vowels that are pronounced together as a single syllable.

Here are some examples of vowel diagraphs:

- ai as in "rain"
- ei as in "eight"
- ie as in "pie"
- oa as in "boat"
- oo as in "book"
- ui as in "juice"

Vowel diagraphs can be used to represent a variety of sounds, and their pronunciation can vary depending on the context. For example, the ai in "rain" is pronounced differently than the ai in "fair".

Vowel diagraphs are an important part of English orthography, and they can be challenging for learners to master. However, with practice, students can learn to recognize and pronounce vowel diagraphs correctly.
