latte=1/3 esspresso, 2/3 milk with a little foam on top
Cappuccino has the frothy top with the sprinkly powder on, frappuccino is cold coffee (yuk) , expresso comes in the tiny, pointless little cups and is strong (more of a hit than a drink) and latte is made with lots and lots of milk. So there you go!
