- **ISO 639-3:** `mon`

## Base locale

This is a regional variant of [[locale-mn-001]] (Mongolian), the base/macro locale for this language.

## Pluralization

CLDR plural categories for this locale: **one**, **other** (2 forms).

- **one** — `n = 1` (e.g. 1)
- **other** — everything else (e.g. 0, 2~16, 100, 1000, …)

See [[unicode-messageformat]] for writing plural messages using these categories.

## Translating into this locale

Apply [[locale-mn-001]] with the conventions of Mongolia, where Cyrillic is the official script (the traditional Mongolian script is being re-promoted for official documents).

- **Script:** Cyrillic for everyday text. Where a project requires the traditional Mongolian script, provide it as a separate resource, not as a transliteration of the Cyrillic.
- **Currency:** tögrög (₮), placed after the amount; check CLDR `mn-MN` for number format.
- **Dates:** year-month-day with ordinal month names; the lunar calendar is used for traditional festivals (Tsagaan Sar).
- **Tone:** polite and respectful, with honorifics for elders and officials.

## Common pitfalls

- Mixing Cyrillic and traditional script without a requirement.
- Writing Russian-style date or number formats.
- The general pitfalls in [[locale-mn-001]] also apply.
