The word "quadrillions" is derived from the Latin prefix "quadri-" meaning "four" and the suffix "-illion" denoting an extremely large, indeterminate number. It is a composite word formed by combining these two elements. The prefix "quadri-" refers to the number four, similar to words like "quadrilateral" (a shape with four sides) or "quadruplets" (a group of four offspring born at the same time). The suffix "-illion" is added to the end of numerical prefixes to create words denoting large numbers. Therefore, the word "quadrillions" implies the quantity or number going after one trillion and one quadrillion is equal to four trillion.
