This may make things even simpler ---
Start with the Latin plic meaning jumbled as in complicated and the Latin plex
meaning intricately interrelated as in complex. Then note that the only
difference between modeling and/or comprehening a) a simple system, b) a
complicated montage, and c) a complex system is the capability of the observer
(span of competencies and degree of proficiency in each). The key attributes of
any system (or montage) are extent, variety and amiguity. When the variety of
interrelationships exceed the observer's ability then the complexness of the
system begets angst in the mind of the human. Humans call this complexity,
properly an attribute of the relationship twixt the system and observer. (01)
