Here's a breakdown:
* Vowel: The letters a, e, i, o, and u are vowels.
* Digraph: A pair of letters that represent a single sound.
Examples of vowel digraphs:
* ai: as in rain, pail, wait
* ay: as in day, play, say
* ee: as in see, tree, bee
* ea: as in meat, read, sea
* ie: as in pie, tie, lie
* oa: as in boat, coat, goat
* ou: as in house, mouse, out
* oi: as in coin, boil, join
* oo: as in moon, food, look
Key points about vowel digraphs:
* The sound represented by a vowel digraph may not be the same as the sound of the individual letters. For example, the "ea" in "read" doesn't sound like the "e" in "bed" or the "a" in "cat".
* Vowel digraphs can be used to represent different vowel sounds depending on the context. For example, the "ou" in "house" makes a different sound than the "ou" in "out".
* Vowel digraphs are a common feature of English spelling, and understanding them is crucial for accurate reading and spelling.
