## Base locale

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

## Pluralization

CLDR has no explicit plural rule defined for this language; it falls back to the root rule of a single **other** category (1 form) — every count uses the same word form, as in Japanese or Chinese.

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

## Translating into this locale

Apply [[locale-co-001]] to the Corsican spoken in France.

- **Context:** Corsican is a recognized regional language but is not official; bilingual signs and documents exist in Corsican and French. Use French for official legal text and Corsican alongside it where the project provides both.
- **Typography:** French conventions (non-breaking space before `: ; ! ?`, guillemets) usually apply.
- **Formats:** euro after the amount; day/month/year; 24-hour clock; decimal comma.

## Common pitfalls

- Presenting Corsican as a dialect of Italian or French in material meant for Corsican readers.
- Machine-translating from French without review.
- The general pitfalls in [[locale-co-001]] also apply.
