## Numerals

The most basic numerals in toki pona are these words:

* ala - 0, nothing
* wan - 1
* tu - 2
* mute (many) - 3 or more
* ale (all) - everything, endless

This is, quite obviously, a very limited system. But it is not unique to toki
pona: languages from some hunter-gatherer societies stop their numerals at
three, two or even one. (In fact, the Pirahã language is reported to only have
had words for "small quantity" and "large quantity", the values of which change
based on context.)

However, there is also a second, additional system that is officially defined,
and commonly used, to describe larger numbers. It repurposes some of toki pona's
words as additional numerals:

* ala - 0
* wan - 1
* tu - 2
* luka (hand) - 5
* mute (many) - 20
* ale (all) - 100

In this system, words are added or repeated in order to form numbers. For
example, 42 is "mute mute tu" (20+20+2) and 18 is "luka luka luka tu wan"
(5+5+5+2+1).

As you can see, this is still a rather limited system. Just to name the year in
which this page was originally written (2020), it would require one to repeat
the word "ale" twenty times and add one "mute" at the end.

These limitations are all part of toki pona's philosophy of simplifying thought
and avoiding unnecessary detail. Some people have tried coming up with other
numeral systems, but none have found widespread acceptance.

## Using numerals

Regardless of the specific system, numerals are treated as adjectives and added
at the end of nouns or noun phrases:

> soweli wan -- one animal

> waso lili tu -- two small birds

For ordinal numbers (first, second...), the word "nanpa" followed by the number
is used.

> jan nanpa wan -- first person

> tomo nanpa mute luka luka wan -- 31st house (or house #31)

The phrase "nanpa wan" is sometimes used along with adjectives as a superlative
modifier:

> nena (Ewelesu/Somolunma) li nena suli nanpa wan lon ma ale. -- Mount
> (Everest/Chomolungma) is the largest mountain in the whole world.

## The calendar

In combination with "tenpo", the words "suno", "mun" and "sike" are commonly
used to describe periods of time:

> tenpo suno -- day ("sun time")

> tenpo pimeja -- night ("dark time")

> tenpo mun / tenpo sike mun -- month ("moon time / moon cycle")

> tenpo sike / tenpo suno sike -- year ("circle time / sun circle time").

## nanpa

In addition to being used for ordinal numerals, the word "nanpa" itself can mean
"number" or "digit". For example,

> ilo nanpa -- calculator ("number device")

> nanpa pona -- score/points ("good numbers")

Of course, one has to be careful then, because using actual numerals in this
case would be confusing. For example, would "ilo nanpa tu" mean "second tool"
or "two calculators"? In the latter example, reshuffling the words into "ilo tu
nanpa" could work.

## Weather

When talking about weather, the commonly used sentence is "[noun] li lon", which
literally means "[noun] exists" and translates to "It is [noun]y". Examples:

> suno li lon. -- It is sunny.

> telo sewi li lon. -- It is rainy. ("Sky water" exists.)

> seli li lon. -- It is warm.

> lete li lon. -- It is cold.

## Dialectal differences

> %info%
> This part of the document describes how certain toki pona courses differ in
> explaining certain ideas, or how communities differ in using them.

Different courses differ on how to write ordinal numbers.

The official book and the "12 days of sona pi toki pona" videos suggest simply
adding "nanpa", followed by the number, while the "o kama sona e toki pona!"
course suggested adding "pi nanpa" and the number.

> jan nanpa wan -- first person

> jan pi nanpa wan -- first person 

In the community, the former way seems slightly more widespread, so this course
will follow its example.
