Martinet originates from the French word 'martinet', which refers to a type of whip or a strict disciplinarian. The term is derived from the name of a 17th-century French army officer, Jean Martinet, who was known for his strict discipline and training methods. Thus, a 'martinet' refers to someone who demands strict adherence to rules and discipline.
