Morphology

nonillion = million (semi-transparent) = non + illion

Built from the numeric prefix 'non-' (nine) plus the '-illion' series (derived from 'million'); the construction signals a high-order named number, but deriving the exact count of zeros requires familiarity with the short/long scale conventions.

Etymology

Nonillion comes from Latin nonus ('ninth') and the ending -illion, as in million. As the ninth -illion, in the short system used in the US it is 1 followed by 30 zeros, while in some European countries the long system gives it 1 followed by 54 zeros, so the name shows its place among very large numbers.
