Etymology

Origin of hierarchy

First recorded in 1350–1400; Middle English jerarchie, from Middle French ierarchie, gerarchie, from Medieval Latin (h)ierarchia, from Late Greek hierarchía “stewardship of sacred rites, rule or power of the high priest,” equivalent to hier(o)- “holy, sacred” + -archía, a combining form meaning “rule”; see hier(o)-, -archy

Explanation

Hierarchy describes a system that organizes or ranks things, often according to power or importance. At school the principal is at the top of the staff hierarchy, while the seniors rule the student hierarchy. Also known as a pecking order or power structure, a hierarchy is a formalized or simply implied understanding of who's on top or what's most important. All that sorting and ranking can be helpful if you're a business administrator, but if you find yourself arranging all the produce in your fridge according to a hierarchy of color, size, and expiration date, you might want to consider visiting a therapist.
