Cyclopaedia → It is formed from "cyclus" (from Greek "kyklos", meaning circle) and "paideia" (from Greek "paideia", meaning education or upbringing). The word refers to a comprehensive reference work that encompasses a wide range of knowledge, organized in a circular or systematic manner.

Memory Tip

Imagine a circle of knowledge ('cyclus') that provides a complete education ('paideia') — that's what a cyclopaedia offers.
