Alice can say "cookie" clearly. When I pick her up at school the first thing she does is run to me and say "Go". On the way home (i.e. implementation of the "Go" request) Alice's next request is "More", by which she is requesting a snack. She can almost say snack but due to the importance of the request she doesn't chance it with new words and uses "More". I have been suggesting options to her on the way home and she has learned to say, "Cookie", which is a favored option. So when we get home (i.e. "Go" accomplished) I can implement the "More" request with a cup of Milk, she is still working on that one, and a cookie which she proudly repeats as she munches it down.
