Numerals are based on a base-8 counting system, with a slight base-16 tendency.
The standalone forms of the numerals are as follows:
| Orthography | IPA | value |
|---|---|---|
| er | ɛr | one |
| aht | ɑxt | two |
| hreis | xʀ̥eɪs | three |
| shtehr | ʃtɛxʀ̥ | four |
| hrvat | xʀ̥vat | five |
| esht | ɛʃt | six |
| sheŋt | ʃɛŋt | seven |
| vaht | vɑxt | eight |
| Orthography | IPA | value |
|---|---|---|
| vaher | ˈvɑxɛr | nine |
| vahaht | ˈvɑxɑxt | ten |
| vahreis | ˈvɑxʀ̥ejs | eleven |
| vashtehr | ˈvɑʃtɛxʀ̥ | twelve |
| vahrvat | ˈvɑxʀ̥vɐt | thirteen |
| vahesht | ˈvɑxɛʃt | fourteen |
| vasheŋt | ˈvɑʃɛŋt | fifteen |
| ashen | ˈaʃən | sixteen |
Beyond 16, the numbers from 1 to 7 are suffixed to a series of multiples of eight to form numbers.
| Orthography | IPA | value |
|---|---|---|
| ashen | ˈaʃən | sixteen |
| hreishen | ˈxʀ̥eɪʃən | twenty-four |
| shtehreshen | ˈʃtɛxʀ̥əʃən | thirty-two |
| hrvashen | ˈxʀ̥vaʃən | forty |
| eshteshen | ˈɛʃtɛʃən | forty-eight |
| sheŋshen | ˈʃɛŋʃən | fifty-six |
| uhren | ˈuxʀ̥ən | sixty-four |
For example, to form the word for seventeen, ashen is suffixed with er to form ashener. To form the word for eighteen, ashen is suffixed with aht to form ashenaht. Similarly, to form the word for forty-one, hrvashen is suffixed with er to form hrvashener.
After uhrensheŋt (71), subsequent numbers are formed by multiple words, consisting of uhren followed by any of the above numbers starting from vaht. So 72 is uhren vaht, 73 is uhren vaher, …, and 80 is uhren ashen. This scheme goes up to uhren sheŋshensheŋt (127).
Following this, numbers are formed from the multiples of uhren (64), followed by the numbers 1-64 as above.
| Orthography | IPA | value |
|---|---|---|
| aht uhren | ˈɑxt ˌʔuxʀ̥ən | 128 |
| hreis uhren | xʀ̥eɪs ˌʔuxʀ̥ən | 192 |
| shtuhren | ˈʃtuxʀ̥ən | 256 |
| hrvat uhren | ˈxʀ̥vat ˌʔuxʀ̥ən | 320 |
| esht uhren | ˈɛʃt ˌʔuʀ̥ən | 384 |
| sheŋt uhren | ˈʃɛŋt ˌʔuʀ̥ən | 448 |
While it is possible to express 256 = 64×4 as shtehr uhren, native speakers use shtuhren (256) instead. This is one of the tendencies towards base-16 counting, as 256 = 16×16.
For example, 200 = 192 + 8 = hreis uhren vaht; and 300 = 256 + 40 + 4 = shtehr uhren hrvashenshtehr.
These are the forms used for cardinal numbers.
For forming compounds, the combining form of the numerals are used:
| Orthography | IPA | value |
|---|---|---|
| heŋ- | xɛŋ | one-, single- |
| ahr- | ɑxʀ̥ | two-, double- |
| hra- | xʀ̥ɐ | three-, tri- |
| shtehre | ʃtɛxʀ̥ə | four-, tetra- |
| hrva(t)- | xʀ̥vaθ | five-, penta- |
| eshte- | ˈɛʃtɛ | six-, hexa- |
| sheŋ- | ʃɛŋ | seven-, hepta- |
| vahr | vɑxʀ̥ | eight-, octa- |
A linking /g/ is inserted after heŋ- and sheŋ- if followed immediately by a vowel.
The combining form hrvat- [xʀ̥vɐθ] is used if immediately followed by a consonant; otherwise, hrva [xʀ̥vɐ] is used instead.
