a state of complete confusion and disorder
n

Etymology
the word 'chaos' entered english in the late 15th century via latin from the ancient greek word 'khaos', meaning 'gaping void' or 'abyss'. in greek mythology and early cosmology, it referred to the primeval, formless state preceding the ordered universe. the semantic journey from a specific cosmic concept to its modern meaning of utter confusion and disorder is a metaphorical extension, reflecting the idea of a state lacking any organization or structure. this abstract sense became dominant in english usage from the 17th century onward.
Analysis
this word is a direct loanword from greek and is not productively segmented using modern english spelling elements.
