Some sonnets do not use the letter which
Begins the common list of English letters.
Such sonnets seem uncommon. Here's the hitch:
This letter's used so much! The old typesetters
Counted it third in frequency of use -
No big surprise, since - by itself - it forms
The commonest of words when on the loose.
You just might find the letter's sound's occurred,
Without its being there. It seems cliche,
But English spelling's nuts! Some well-formed word
Will often rudely, crudely disobey
The Rules of Phonics, to somehow convey
The sound we should expect to find with A.
