A word salad

I take it you already know
Of tough and bough and cough and dough
Others may stumble, but not you
On hiccough, thorough, laugh, and through 

And cork and work and card and ward
And font and front and word and sword
Well done! And now if you wish, perhaps
To learn of less familiar traps

Beware of heard, a dreadful word
That looks like beard and sounds like bird
And dead: it’s said like bed, not bead
For goodness sakes don’t call it deed

Watch out for meat and great and threat
They rhyme with suite and straight and debt 
A moth is not a moth in mother
Nor both in bother, broth in brother

And here is not a match for there
And dear and fear for bear and pear
And then there’s dose and rose and lose
Just look them up, and goose and choose

And do and go, then thwart and cart
Come, come, I’ve hardly made a start!
A dreadful language? Man alive!
I mastered it when I was five
