-illion

== English == === Etymology === Back-formation from million, then used in billion, trillion, quadrillion, each from French, ultimately from Italian mille (“thousand”) and the augmentative suffix -one. -illion was segmented from million as if mi- was a prefix, and -illion the stem. === Suffix === -illion Combined with Latin prefixes for names of integers in order to form names of powers of a million. ‎bi- + ‎-illion → ‎billion ‎tri- + ‎-illion → ‎trillion Added to various nonsense syllables to indicate an arbitrarily very large number. ==== Usage notes ==== The words formed with this suffix may mean either 1 , 000 , 000 n {\displaystyle 1,000,000^{n}} or 1000 n + 1 {\displaystyle 1000^{n+1}} in different nations and languages. Hence billion can mean “one million million” or “one thousand million”.
