Etymology Origin:
Derived from Latin corrugare ("to wrinkle together"), combining cor- (intensifying prefix) and ruga ("wrinkle"). The term evolved to describe materials (e.g., metal, cardboard) pressed into alternating ridges and grooves for structural reinforcement. The suffix -ated marks its adjectival form in English.
