Complexity describes the behaviour of a system or model whose components interact in multiple ways and follow local rules, meaning there is no reasonable higher instruction to define the various possible interactions. 
The stem of the word complexity i.e. Complex is composed of the Latin words com (meaning: "together") and plex (meaning: woven). This is best contrasted with Complicated where plic (meaning: folded) refers to many layers. A complex system is thereby characterised by its inter-dependencies, where as a complicated system is characterised by its layers.
