===Higher numbers===
At numbers beyond the thousands, the international roots ''miliono'' (million) and ''miliardo'' (milliard) are used. Beyond this there are two systems: A ''[[Long and short scales|billion]]'' in most English-speaking countries is different from a ''billion'' in most other countries (10<sup>9</sup> ''vs.'' 10<sup>12</sup> respectively; that is, a thousand million ''vs.'' a million million). The international root ''biliono'' is likewise ambiguous in Esperanto, and is deprecated for this reason. An unambiguous system based on adding the Esperanto suffix ''-iliono'' to numerals is generally used instead, sometimes supplemented by a second suffix ''-iliardo:''<ref>"[https://reta-vortaro.de/revo/art/bilion.html biliono]" at Reta Vortaro</ref>

:10<sup>6</sup>: ''miliono''
:10<sup>9</sup>: ''miliardo'' (or ''mil milionoj'')
:10<sup>12</sup>: ''duiliono''
:10<sup>15</sup>: ''duiliardo'' (or ''mil duilionoj'')
:10<sup>18</sup>: ''triiliono''
:10<sup>21</sup>: ''triiliardo'' (or ''mil triilionoj'')
:''... etc.''

Note that these forms are grammatically nouns, not numerals, and therefore cannot modify a noun directly: ''mil homojn'' (a thousand people [accusative]) but ''milionon da homoj'' (a million people [accusative]).
