The word "corrugated" refers to something that has a wrinkled or ridged appearance, usually in a regular pattern. It's often used to describe certain types of cardboard or metal sheets that have a wavy texture, which makes them stronger and more durable. So, you might hear this word used when talking about corrugated cardboard boxes, which are commonly used for shipping and storage, or corrugated metal roofing, which is used to cover buildings.
