The adjective easy can describe anything that comes without too much effort, like your baseball team's easy win, or your dad's easy recipe for nachos.
Something that's easy isn't at all difficult — it just seems to fall into place. There's also a sense of slowness, casualness, and a lack of worry, like getting an easy "A" in your History of Hip Hop class. Easy comes from the Old French word aisie, "comfortable, rich, well-off," an easy way to live indeed. The only thing about easy that's less than simple is remembering to change the y to an i for variations like easier and easiest.
