The word "encyclopaedia" comes from mistaken Classical Greek "ἐγκύκλιος παιδεία", transliterated "enkyklios paideia"; "enkyklios" (ἐγκύκλιος), meaning "circular, recurrent, required regularly, general" + "paideia" (παιδεία), meaning "education". Together, the phrase literally translates as "common knowledge" or "general knowledge". Copyists of Latin manuscripts took this phrase to be a single Greek word, "enkuklopaedia", with the same meaning, and this spurious Greek word became the New Latin word "encyclopaedia", which in turn came into English. Though the notion of a compendium of knowledge dates back thousands of years, the term was first used in the title of a book in 1517 by Johannes Avenarius: Encyclopedia orbisque doctrinarum, hoc est omnium artium, scientiarum, ipsius philosophiae index ac divisio, and in 1541 by Joachimus Fortius Ringelbergius, Lucubrationes vel potius absolutissima kyklopaideia (Basel, 1541). The word encyclopaedia was first used as a noun in the title of his book by the Croatian encyclopedist Pavao Skalić in his Encyclopaedia seu orbis disciplinarum tam sacrarum quam prophanarum epistemon (Encyclopaedia, or Knowledge of the World of Disciplines, Basel, 1559). One of the oldest vernacular uses was by François Rabelais in his Pantagruel in 1532.

Several encyclopedias have names that include the suffix -p(a)edia, e.g., Banglapedia (on matters relevant for Bengal).

In British usage, the spellings encyclopedia and encyclopaedia are both current. Although the latter spelling is considered more "proper" by British speakers, the former is becoming increasingly common in British English, in part due to the spread of American English. In American usage, only the former is commonly used. The spelling encyclopædia—with the æ ligature—was frequently used in the 19th century and is increasingly rare, although it is retained in product titles such as Encyclopædia Britannica and others. The Oxford English Dictionary (1989) records encyclopædia and encyclopaedia as equal alternatives (in that order), and notes the æ would be obsolete except that it is preserved in works that have Latin titles. Webster's Third New International Dictionary (1997–2002) features encyclopedia as the main headword and encyclopaedia as a minor variant. In addition, cyclopedia and cyclopaedia are now rarely used shortened forms of the word originating in the 17th century.
