Discuss English vowels in detail.

The 5 English vowels are a, e, i, o, and
u.

Each can have a long sound and a short sound. The long
sound primarily sounds as an identification of the vowel. Long vowel sounds are often in
play when two vowels are working together. For example, the words paid, play,
and made all contain the long A sound, and they are
working with another vowel somewhere in the word.

Short
sounds are often used when they work alone and on their own. For example, the words
dot, on, and
shod.

Sometimes, vowels work with
consonants or other vowels to make a different sound that doesn't follow the above
rules, but makes another sound. Some of those combinations in words are aw,
au, oo, ow, and ou.

I
recommend searching the term phonics, and then within that, search vowel
rules.
