Morphology
siderography = sidero + graphy
The word is built from classical combining forms, but the specialized meaning 'steel-plate engraving/printing' is not directly inferable for most learners.
Etymology
Siderography comes from the Greek parts sidero- meaning 'iron' and -graphy meaning 'writing', so it literally means 'writing on iron'. That's why siderography refers to a method of engraving and printing on steel plates to make banknotes and documents hard to fake.
