Morphology
cryptography = crypto + graphy
The word is built from classical combining forms meaning 'hidden' and 'writing', so the sense is partly guessable, but the modern technical meaning is specialized and not fully transparent to an average learner.
Etymology
Cryptography comes from Greek parts crypto- meaning 'hidden' and -graphy meaning 'writing', so it literally means 'hidden writing' and explains why cryptography is the science of making and solving secret messages.
