Regional variants

This is the base/macro locale for Corsican. Region-specific variants in this dataset:

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

Corsican (Corsu) is a Romance language closely related to Tuscan Italian, spoken on Corsica. It is a recognized regional language in France and has no single fully codified standard; there are northern and southern varieties. This guidance is lower-confidence than for major languages; have a native reviewer check it.

Translate ideas, not words.

  • Translate into Corsican directly. French calques are common and weaken the text; Italian vocabulary is a closer model than French for many abstract words.
  • Re-express French and English idioms by meaning.

Grammar and register.

  • Nouns have gender; the definite articles include "u", "a", "i", "e"; the language uses "tù" for the informal singular and "voi" for the plural and the polite singular in traditional use. Confirm the form with a native editor.
  • Word order is flexible but SVO is neutral.

Orthography and typography.

  • Follow the spelling in use in Corsican teaching and the Collectivité de Corse's language office materials; check the dictionary for "ghj", "chj", and "sc" digraphs, which are not French.
  • French typography conventions (non-breaking space before : ; ! ?, guillemets) are applied in France-based publications.
  • Currency euro; day/month/year.

Common pitfalls

  • Writing French or Italian forms where a Corsican word exists.
  • Mixing northern and southern spelling features without reason.
  • Applying French syntax to Corsican sentences.
