Start with the word corn, and the whole name opens up. Corn once meant a small grain, and grains of coarse salt were what you packed round a piece of beef to stop it going bad. So corned beef is salted beef: meat that someone treated, long before fridges, so it would last. Every use sits on that one picture of preserved meat. What changes from country to country is how the preserving finishes — in a pot of brine that you slice from, or pressed into a sealed tin on a shelf.
