Dummy vs. Mannequin: What's the Difference?

Table of Contents

Mannequin
A mannequin (also called a manikin, dummy, lay figure or dress form) is an often articulated doll used by artists, tailors, dressmakers, windowdressers and others especially to display or fit clothing. The term is also used for life-sized dolls with simulated airways used in the teaching of first aid, CPR, and advanced airway management skills such as tracheal intubation and for human figures used in computer simulation to model the behavior of the human body. During the 1950s, mannequins were used in nuclear tests to help show the effects of nuclear weapons on humans.
Mannequin comes from the French word mannequin, which had acquired the meaning “an artist’s jointed model”, which in turn came from the Flemish word manneken, meaning “little man, figurine”. In early use in the United Kingdom, it referred to fashion models themselves, the meaning as a dummy dating from the start of World War II.
