How many sounds does a vowel digraph make?

That's a bit of a tricky question! It depends on how you define "sound" and "vowel digraph."

Here's a breakdown:

* Vowel Digraph: Two letters that represent a single vowel sound. Examples: "ai" in "rain," "ea" in "bread," "oo" in "moon."

* Single Sound: One distinct sound that your ears perceive.

So, a vowel digraph usually represents one single sound.

However, some vowel digraphs can represent *slightly* different sounds depending on the context. For example:

* "ea" can sound like /ee/ in "sea" but like /e/ in "head"

* "ou" can sound like /ow/ in "cloud" but like /u/ in "could"

Therefore, it's more accurate to say that a vowel digraph generally represents one sound, but that sound can vary slightly depending on the word.
