The Greek word khaos originally means the "the gaping"; it points in the direction of a measureless, supportless, and groundless yawning open...For us, the chaotic means the jumbled, the tangled, the pell-mell. Chaos means not only what is unordered but also entanglement in confusion, the jumble of something in shambles. In its later significance, chaos also always means some kind of "motion."
