An array is a display of something — usually something varied. You might encounter an array of cereal brands in the cereal aisle of the grocery store. Your head says to choose the Crunchy Oats 'n' Bran, but your heart wants the Sugar-Coated Chocopuffs.

Although the word array comes from the Old French areyer, "to put in order," an array often just comes together. It can be an intentional design of people or features — everything from software packages to fashion shows can have an "impressive array" of components. Or, an array can fall together in nature or by chance: "the clouds became an array of beautiful shapes after the storm."
