JKR's play on words, other than the spells/charms

I just love JKR's play on words. The ones in the spells/charms are more obvious. I was thinking more along the lines of "Slytherin" which immediately makes one think of a snake that slithers in. I also noticed this in "Gringotts" "gold ingots". I know there are more. Has this been discussed before? If not, are there any other words like this that others have noticed?

Something to think about besides the scream, she said distractedly.
