Centillion appears to be the highest name ending in -'illion' that is included in these dictionaries. Long scale: French Canada, older British, Western & Central EuropeĪpart from million, the words in this list ending with - illion are all derived by adding prefixes ( bi-, tri-, etc., derived from Latin) to the stem - illion.Short scale: US, English Canada, modern British, Australia, and Eastern Europe.English also has many words, such as 'zillion', used informally to mean large but unspecified amounts see indefinite and fictitious numbers. Indian English does not use millions, but has its own system of large numbers including lakhs and crores. For example, the statement 'There are approximately 7.1 octillion atoms in an adult human body' is understood to be in short scale of the table below (and is only accurate if referring to short scale rather than long scale). However, these somewhat rare names are considered acceptable for approximate statements. Names of numbers above a trillion are rarely used in practice such large numbers have practical usage primarily in the scientific domain, where powers of ten are expressed as 10 with a numeric superscript. These naming procedures are based on taking the number n occurring in 10 3 n+3 (short scale) or 10 6 n (long scale) and concatenating Latin roots for its units, tens, and hundreds place, together with the suffix -illion. Most English variants use the short scale today, but the long scale remains dominant in many non-English-speaking areas, including continental Europe and Spanish-speaking countries in Latin America. Two naming scales for large numbers have been used in English and other European languages since the early modern era: the long and short scales.
