Perforation 1

Perforation 1 (from the Latin perforatio - “drilling”; synonym - perforation) is the piercing or punching of a hole in any object.

Perforation may occur naturally or be the result of a deliberate action. Examples of perforation include making holes in paper, cardboard, fabric, plastic, and other materials using drills, needles, or other sharp instruments.

The term "perforation" is also used in medicine to refer to perforation of organs and tissues, such as perforation of the intestine or eardrum. In geology, perforation refers to the formation of holes and voids in rocks under the influence of water or other natural processes.

Thus, perforation 1 means creating a through hole in an object by piercing, punching, or naturally breaking through.
