Etymology

Suffix

 * 1) Combined with Latin prefixes for names of integers in order to form names of powers of a million or of a thousand greater than 1,000,000. Thus we have the names billion, trillion, etc.
 * 2) Added to various nonsense syllables to indicate an arbitrarily very large number.

Usage notes

 * The words formed by combining the Latin prefix for the name of an integer $$n$$ ($$n > 1$$) with this suffix may mean $$1,000,000^n$$ or $$1000^{n + 1}$$ depending on national practices. Hence billion can mean “million million” or “thousand million”. See the usage notes at Wiktionary’s appendix on numbers for more information.
