Morphology

quadrillion = million (semi-transparent) = quadri + million

The form shows the 'quadri-' element combined with the '-illion' number series so it signals a very large number, but the exact magnitude requires knowledge of numeric naming conventions (short scale = 10^15).

Etymology

Quadrillion comes from the Latin root quadri- meaning 'four' and the familiar -illion from million, because it is the fourth large number name after million. So, in the short-number system used in the United States it means 1 followed by 15 zeros, or 'one thousand trillion'.
