Disorder refers to the concept of an obstructed system or arrangement, either within the realm of the given natural world, or the human-constructed social world. It is an irregular composition or a non-intelligible pattern. Alternatively, it can be thought as the negation or absence of order, which would result in the presence of chaos. As a verb, it becomes synonymous with destroy, disturb and violate. It can also be defined more literally as the condition in which things are not situated in their expected places. The noun, disorder is synonymous with broken, a state of disarray, or confusion. The term’s first appearance in English was in the 15th century. It is a modification of its forerunners, which are the 14th century word disordeiner, O.Fr., and disordinare, M.L., both meaning throw into disorder. The root word which disorder derives from is hordere, mE, a 12th century verb which translates to order, arrange or regulate.
In its broadest sense, the verb, disorder, can be used sparingly to talk about the act of creating a slight offset, or imbalance within a perfect composition, such as the disordering of an organized pile of papers. The word in its adjective form can be used with a similar effect to describe subjects: a disordered life is one which comprises of decadent excessiveness in terms of possessions and an obstructed view of priorities. In this usage, the word means morally irregular, or corrupt. The word disorder can be used to describe both tangible and intangible instances. The noun, disorder, is often used terminologically for medical diagnosis of physical and mental behaviours that are out of the ordinary. Eating disorder pertains to abnormal eating habits that involve either an insufficient or excessive amount of food intake. In psychology, there are a myriad of disorders which define specific abnormal states of the mind, human behaviour and personality types. All of these types of disorders fall under broader categories such a mental disorder, or emotional and behavioural disorder. Such disorders are generally associated with human conditions of distress or disability, which are not considered a part of a person’s normal development. In physics, the term disorder is used to allocate the absence of some symmetry or correlation in any given many-particle system. Disorder is also used terminologically for sociological concepts. Civil disorder is termed to describe any form of disturbance in society caused by a group of people. Results of civil disorder include riots, sabotage, and chaos amongst the public.
