When I was a kid, the local fast food place used to sell a little box of cookies as a sort of quick dessert once we had loaded up on their high-calorie burgers.
One day I was eating out with a friend and happened to notice that on the packet of these little items it said “Chocolaty Chip Cookies”. Not chocolate, “chocolat-y”.
“Why does it say that? What the heck is ‘chocolaty’?” I asked.
“Oh,” said my friend, “it’s not actually chocolate. It’s some kind of chocolate-like thing, and they can’t legally call it chocolate. So they stick the ‘y’ on the end to cover themselves.”
