Quizplus · Accepted Answer

A clipping mask in Illustrator is used to show only a part of the artwork that lies within the shape of the mask, similar to how a stencil, matting, or a hole would allow only certain parts of what's behind them to be seen. A lamp on a desk does not serve as an analogy for this function, as it does not hide parts of an object behind it in a manner that selectively reveals a design or image.
