https://alpha-wiki.win/index.php/Large_number_names_and_the_-illion_sequence
The -illion sequence refers to large number names like million, billion, trillion, and beyond, formed by combining Latin prefixes with the -illion suffix. These terms follow a systematic pattern, with each step being a thousand times larger than the previous one, extending to arbitrarily high numbers.
