Naming Large Numbers

French physician and mathematician Nicolas Chuquet (1445-1488) devised a naming system for large numbers that combined a Latin-based numeric prefix with the suffix "-yllion" (later "-illion") to denote an integer power of one million (1,000,000 = 106 = 1E+06).  The Chuquet System gradually became popular throughout Europe. In the Chuquet System:

"(prefix)illion" = 1,000,000(prefix) = 10(6×prefix)

In the Seventeenth Century, a mutation of the Chuquet naming system evolved in which the Latin-based numeric prefix denoted an integer power of one thousand (1,000 = 103 = 1E+03), but since the name "million" had been used for centuries to represent "a thousand thousand", this system employed a multiplicative offset of one thousand (1,000).  This new system proved more convenient than Chuquet's system, but it lacked the simplicity of the older system.  The new system found favor in France and eventually spread to North America, where it became known as the American System. In the American System:

"(prefix)illion" = 1,000×1,000(prefix) = 1,000(1+prefix) = 10(3×(1+prefix))

In the Twentieth Century, a British modification of the original Chuquet System attempted to make the naming system more convenient. The Modified Chuquet System, in which the suffix "-illiard" is used to denote a number one thousand times greater than the corresponding number with the "-illion" suffix, met with limited success. In the Modified Chuquet System:

"(prefix)illion" = 1,000,000(prefix)[×1,000] = 10((6×prefix)[+3])

We now have three competing English Language number naming systems: the Chuquet System, the American System, and the Modified Chuquet System.  The confusion among the naming systems was aggravated in 1948 when France officially switched back to the Chuquet System, and further confounded in 1974 when the Government of the United Kingdom informally switched to the American System.

Across the three number naming systems, there is general agreement on the spelling of number names up through one centillion.  Please see the Names for Large Numbers.  The names of the multiplicative inverses of the integer powers of one thousand (1,000) are formed by adding the suffix "-th" to the number name. Please see the Integer Powers of 1000 for a comparison of the three systems.

American mathematician Landon Curt Noll (1960-) has proposed standard names for even larger numbers.  While Noll's system has yet to be widely accepted, it is a heroic attempt to put names on hippo­poto­monstro­sesqui­pedalian numbers.  Landon has created a webpage that provides an English Language name for any number.

If I was "King of the Universe," I would dump the name "billion" and use a system in which "(prefix)illion" = 1,000prefix = 103×prefix, but then all we need is one more way to name large numbers.
