There is more than one type of chaos.
In mathematics, most weather patterns are described using formulae now known as ‘chaotic’ – more complex than simple linear changes or simple curvilinear functions.
Personally, I harbor the belief that everyone under 5years old is a chaotic creature compared to adults, but that little kids are fortunately often ‘beautiful, gentle chaotic beings’ rather than:
Train wrecks and the debris of terrorist attacks are considered to be chaos, but of a vicious intentional nature rather than being of the same nature as the above.
Chaos can be disorder, or discordianism, or entropy or anything that goes against a structure.
I don’t know the word for it in Spanish, but in German we’re in luck because it is ‘kaos’, I think.
