How do Greek roots give you clues to the meaning of oligarchy?

The word "oligarchy" is formed from two Greek roots:

* ὀλίγος (oligos): meaning "few," "small," or "little."

* ἄρχω (archo): meaning "to rule," "to govern," or "to command."

Therefore, "oligarchy" literally means "rule by the few." The Greek roots directly reveal the core concept of a system of government where power is concentrated in the hands of a small elite group.
