Does Cacophony Rhyme With Homophone?

Every couple months or so
I’ll learn a word I didn’t know
I’ve mispronounced inside my head
Sounds quite another way instead
Than what I’ve likely said out loud
Which makes me feel a bit…not proud.
Am I alone? I’d take a poll,
But fear — excuse the hyperbole —
That I might die of shame if ever
It were proven I’m less clever
Than I act alone at home.
For gaucheness, I’m the epitome.
It’s awkward, but predictable;
At least it’s not indictable.
