I’ve been looking for this poem for a while and just ran into it on Reddit. Our language really is atrocious, isn’t it?
“Now I surely will not plague you
With such words as plaque and ague.
But be careful how you speak:
Say break and steak, but bleak and streak;
Cloven, oven, how and low,
Script, receipt, show, poem, and toe.
Hear me say, devoid of trickery,
Daughter, laughter, and Terpsichore”
The rest of it is here. Don’t worry, there’s lots more where the above came from.
