What does encyclopedic mean?
Encyclopedic is an adjective describing something remarkably comprehensive in scope, range, or detail — most commonly applied to a person's knowledge or memory. To say someone has encyclopedic knowledge is to suggest they have mastered a vast body of information across many subjects, as though their mind were an entire reference library. The word can also describe things that resemble or relate to an actual encyclopedia, such as encyclopedic dictionaries or surveys. It carries a strongly positive connotation, implying depth and breadth rather than mere accumulation of facts, and it appears frequently in formal writing, journalism, and academic prose. Derived from the Greek enkyklios paideia, meaning a well-rounded or circular education, the word itself embodies the ideal of complete learning. A related adverb, encyclopedically, exists but is far less common.
adjectiveRelating to or characteristic of an encyclopedia; comprehensive in scope or knowledge, covering a wide range of subjects in thorough detail.

"He has an encyclopedic memory for film trivia."
"The report offers an encyclopedic survey of twentieth-century architecture."
The word traces back to the Greek idea of a 'circle of learning' (enkyklios paideia) — the notion that true education forms a complete, rounded whole.

Etymology of encyclopedic
Encyclopedic derives from the noun encyclopedia, which entered English in the early modern period from post-classical Latin encyclopaedia. The Latin term was borrowed from Greek enkyklios paideia, meaning a circular or well-rounded course of instruction. The adjective form developed later to describe both the nature of an encyclopedia and, more broadly, anything comprehensive in scope.
