Esperanto

Suffix

-iliono

1. Used with a cardinal number to indicate numbers greater than a million. Specifically, it indicates the number 10^6x (where x is the cardinal number), and it corresponds with long scale usage in English.

   duiliono - billion (10¹²)

   triiliono - trillion (10¹⁸)

Usage notes

• Only works with cardinal numbers two (du) and greater. For 10⁶, see miliono.
• This suffix usage is proposed by the most recent version of the PIV, but is not considered official.

For intermediate powers of 10³, mil may be used: mil duilionoj (10¹⁵), mil triilionoj (10²¹). But see also -iliardo.
