What does cyclopaedic mean?
Cyclopaedic is a formal adjective describing information, knowledge, or a work that covers an unusually wide range of subjects. It is closely related in meaning to encyclopedic, suggesting breadth, systematic organization, and often considerable detail. The word appears naturally in phrases such as cyclopaedic knowledge and cyclopaedic survey, particularly in scholarly, historical, or literary contexts. Its use can convey erudition and authority, although it may sound old-fashioned or unnecessarily expansive where comprehensive would suffice. Cyclopaedic is chiefly associated with British spelling; the more familiar American form is cyclopedic, and encyclopedic is now more common generally. The word is useful when emphasis is placed not merely on knowing a particular fact but on encompassing a whole field or body of knowledge. Its classical formation also links it to the Greek concept of a circle or comprehensive cycle of learning, reflecting the ambition to bring disparate subjects together within one organized account.

Where does cyclopaedic come from?
Cyclopaedic was formed in the 19th century by adding the suffix -ic to cyclopaedia. Cyclopaedia draws on Greek kyklos, meaning “circle,” and paideia, meaning “education” or “learning.” The related English words encyclopedia and encyclopaedia come through the same Greek educational tradition, in which knowledge is conceived as a complete or circular system.
