'chaoticness' originates from English, specifically the combination of the adjective 'chaotic' and the noun-forming suffix '-ness', where 'chaotic' means 'relating to chaos' and '-ness' forms an abstract noun indicating a state or quality.

'chaotic' entered English via Modern Latin/French formations from the Greek word 'χάος' (khaos), and the productive English suffix '-ness' (from Old English '-nes(s)e') was later attached to form 'chaoticness' as a nominalization meaning 'the state of being chaotic'.

The root 'chaos' originally referred to a 'gaping void' or 'vast emptiness' in ancient Greek, and over time its sense shifted toward 'confusion' or 'disorder', which is reflected in the modern meaning of 'chaotic' and thus 'chaoticness'.
