The end of its first line we say
Is indicated by an “a”.
And from then on a matching rhyme
Will be marked “a” but at some time
A different ending we will see
And note that different sound as “b”.
Then writing “c” is what we do
For sounds unlike the other two.
So you can see we’ve used today
Four different letters in this way:
aa, bb, cc, dd
aa again, then twice a “c”.
A little word of warning here
Our eye can sometimes fool our ear.
An “eye rhyme” looks as though the sound
Will be the same but you’ll have found
With “tough” and “through” this isn’t true;
One sounds like “fluff” and one like “do”.
So analyse and have some fun
While scheming – please excuse the pun.
