Esperanto is a constructed international auxiliary language. Invented by Dr. Ludwik Łazarz Zamenhof in 1887, it counts about 100,000 very active speakers, 2 million fluent speakers and one thousand native speakers. Mostly based on European languages (French, German, Polish and Russian), it is written with a modified version of the Latin alphabet, and is very regular in its forms.

Numbers in Esperanto: Esperanto numbering rules

Each culture has specific peculiarities that are expressed in its language and its way of counting. The Esperanto is no exception.

Working with numbers and a foreign language like Esperanto at the same time is one of the best ways to train our little gray cells, so let's see what rules you need to apply to number in Esperanto

.

Digits from zero to nine are specific words, namely nul [0], unu [1], du [2], tri [3], kvar [4], kvin [5], ses [6], sep [7], ok [8], and naŭ [9].

The tens are formed by adding the ten word (dek) after the matching digit, with the exception of ten where the unit is implicit: dek [10], dudek [20], tridek [30], kvardek [40], kvindek [50], sesdek [60], sepdek [70], okdek [80], and naŭdek [90].

Numbers from twenty-one to ninety-one are constructed by saying the ten first, followed by the digit separated with a space (e.g.: dudek kvin [25], kvardek ses [46]).

The hundreds are built exactly the same way as the tens (e.g.: cent [100], ducent [200], tricent [300]…), as well as the thousands (e.g.: mil [1,000], dumil [2,000], trimil [3,000]…).

The Esperanto language follows the long scale system for naming big numbers: every new word greater than a million is one million times bigger than the previous term. Thus, miliardo is equivalent to 10⁹ (one billion in the US), a trillion (10¹²) is said biliono, and a quadrillion (10¹⁵) is said triliono. Big scale numbers are substantival number words, or numbers if the form of a noun. Thus, they have the -o ending of Esperanto substantives, and they take the -j suffix in their plural form: one million is unu miliono, and two millions is du milionoj.
