There are only five true vowels. Their names are:

a	e	i	o	u
and their short sounds are:
Apple	Elephant	Igloo	Octopus	Umbrella
These are very important letters because there cannot be a word or a syllable without a vowel, ( NB y acts as both a vowel and a consonant ).
The long vowel sounds say their name:
		9
Tape	Mere	nine	Nose	Cube
There are spelling choices for each of the long vowels:
a,	e,	i,	0,	u,
a-e,	e-e,	i-e,	o-e,	u-e,
ai,	ee,	igh,	oa,	oo,
ay,	ea,	ie,	oe,	ue,
	ey,	y,	ow,	ew,
	ie,
	y,
Remember:	When two vowels go out walking, The first one often does the talking, But there are exceptions, as always.
