Etymology
Origin of corrugated
First recorded in 1585–95; corrugate ( def. ) + -ed 2 ( def. ) for the adjective; corrugate ( def. ) + -ed 1 ( def. ) for the verb
Explanation
Corrugated means molded into tight ridges and valleys. You've probably seen corrugated cardboard or corrugated metal roofs. Materials are put into a corrugated shape to ensure elasticity and strength — cardboard boxes hold their shape because the cardboard is reinforced with a corrugated layer inside the two flat pieces. To remember corrugated, think about corduroy pants — which also have ridges and valleys. If you're lucky enough to have had ribbon candy, that's corrugated as well.
