### Etymology

From *nā* ‘ten’ and *kaigu* ‘thousand’

### Pronunciation

(*Grayis*) IPA: /naˈkai̯.gu/

### Number

**nakaigu**

- ten thousand.
- 6,561.
*Because Grayis uses a nonal (base-9) number system, this represents the numeric value of 6,561, but the semantic value of ‘ten thousand’ (10×10³).*
