Definition of break down

The origin of the phrase "break down" dates back to the mid-16th century, where it was first used to describe the physical collapse or failure of a machine. This definition is still relevant today as "break down" is commonly used to describe the failure or malfunction of mechanical equipment, such as cars or appliances. However, over time, the phrase has also taken on a different meaning in the context of human behavior. In psychology, "break down" is used to describe a loss of emotional and mental stability, often resulting in intense emotional or psychological distress. This usage first emerged in the late 19th century, as the study of psychology began to take shape and provide a framework for understanding human behavior. The connection between the two meanings of the phrase may lie in the fact that a mechanical breakdown can often trigger intense emotions, particularly in situations where something essential to daily life or routine has failed. The use of "break down" to describe the failure of a machine and the subsequent emotional reaction highlights the interconnectedness between physical systems and human feelings, and the way that breakdowns in either realm can be deeply unsettling. In summary, the origin of the phrase "break down" can be traced back to its use in describing mechanical failure, but it has since taken on a second, psychological meaning that reflects the complexity of human experience.
