Word History: A department store mannequin is often not a man and often not little, yet mannequin goes back to the Middle Dutch word mannekijn, the diminutive form of man, "man, person." As for the size of a mannequin, the Middle Dutch word could mean "dwarf" but in Modern Dutch developed the specialized sense of "an artist's jointed model." This was the sense in which we adopted the word (first recorded in 1570), making it another term like easel and landscape taken over from the terminology of Dutch painters of the time. The word borrowed from Dutch now has the form manikin. We later adopted the French version of the Dutch word as well, giving English mannequin, and this is now the form most commonly encountered and the one commonly used for a department store dummy as well as a live model.
