'unencrypted' originates from the prefix 'un-' meaning 'not' and the word 'encrypt,' which comes from the Greek word 'kryptos,' meaning 'hidden.'

'unencrypted' evolved from the combination of 'un-' and 'encrypt,' which was derived from the Greek 'kryptos' through Latin 'crypta' and Old French 'encrypter.'

Initially, 'encrypt' meant 'to hide or conceal,' and 'unencrypted' has consistently meant 'not hidden or concealed.'
