SOUNDS AND LETTERS DONT AGREE

When the English tongue we speak
Why is break not rhymed with freak?
Won't you tell me why it's true
We say sew, but also few?
And the maker of a verse
Cannot rhyme his horse with worse.
Beard is not the same as heard
And core is different from word.
Vaca is cow, but bajo is low
And shoe is never rhymed with foe.
Think of hose and dose and lose.
And think of goose and yet choose.
Think of comb and tomb and bomb
and the babies in the womb.
Doll and roll and home and some,
and, since pay is rhymed with say
Why not paid with said, I pray?
Think of blood and food and good
like a flood of words in a mood.
Mould is not pronounced like could.
Wherefore done, but gone and lone.
Is there any reason known?
To sum up it seems to me
sounds and letters don't agree!!
