Bob and français, gurunet gives both ways of saying ribald,
but lists ribbled first. I've always said RYE-bald.

And yes, grisly is pronounced grizzly. I don't know if this is right, but I tend to put three syllables
into the word gristly: griss-el-ly, just to make the
distinction.

Just thought of one I got laughed at for. I used a long
"i" for the first syllable in cringing.
