'encyclopedia' originates from the Greek word 'enkuklopaideia,' where 'enkuklios' meant 'circular' and 'paideia' meant 'education.'

'enkuklopaideia' transformed into the Latin word 'encyclopaedia,' and eventually became the modern English word 'encyclopedia.'

Initially, it meant 'general education,' but over time it evolved into its current meaning of 'a comprehensive reference work.'
