Mauritian, Haitian, Seychellois and Réunion Creole: Which Is Which

Search for "Creole" on its own and you will almost always get Haitian. It has by far the most speakers of any French-lexifier creole, the largest online presence and the most learning material, so it fills the results whether or not it is what you wanted.

That causes real confusion, because there are several French-lexifier creoles, they are genuinely related, and they are genuinely different. This page sorts out which is which.

The quick version

Language Where ISO code
Mauritian Creole, Kreol Morisien Mauritius mfe
Rodriguan Creole, Kreol Rodrige Rodrigues, an autonomous part of Mauritius no separate code
Seychellois Creole, Seselwa Seychelles crs
Réunion Creole, kréol rénioné Réunion rcf
Chagossian Creole Chagos Archipelago and the Chagossian diaspora no separate code
Agalega Creole Agaléga, part of Mauritius no separate code
Haitian Creole, Kreyòl ayisyen Haiti and its diaspora hat

The first six are Indian Ocean. Haitian is Caribbean, along with Martinican, Guadeloupean, Louisiana and Guianese Creole. All of them draw their vocabulary chiefly from French, and all of them developed separately, in different places, from different French dialects, with different substrate languages and on different timescales.

Mauritian and Haitian

These are the two most often confused, and they are the furthest apart of any pair on this page. They developed on opposite sides of the world, from different varieties of colonial French, with substrate languages drawn from different parts of Africa, and the two speech communities have had essentially no contact.

The tense and aspect systems are a good illustration. Both languages put separate words before the verb rather than inflecting it, but the words are not the same and they do not line up:

  • Haitian marks past with te, the progressive with ap, and the future with pral(e) or a and va.
  • Mauritian marks past with ti, the progressive with pe, and the future with pou.

So Haitian ap corresponds to Mauritian pe, not to pou, which is the sort of false friend that makes material from one language actively misleading for the other. The writing differs too: Haitian uses accented letters, as in kreyòl, where the Mauritian standard prescribes no diacritics at all.

The practical upshot: a Haitian Creole course, dictionary or translation app will not help you in Mauritius. Given how much of the available material is Haitian, this is worth checking before you buy anything.

Mauritian and Seychellois

These two are close. Seychelles was settled from Mauritius in the eighteenth century, and Seychellois Creole descends from the same Indian Ocean creole that produced Kreol Morisien, which is why speakers of one can generally make a good deal of sense of the other.

They are nonetheless treated as separate languages, with separate ISO codes, separate standardised orthographies and separate official positions. Seychellois Creole has a much stronger constitutional footing. Article 4(1) of the Constitution of Seychelles provides that "the National languages of Seychelles shall be Creole, English and French", which is a status Kreol Morisien has no equivalent of in Mauritius.

Worth saying that no published study measures how much speakers of each actually understand of the other, so treat confident percentages with suspicion here as well.

Mauritian and Rodriguan

This one has changed recently, and most sources have not caught up.

As late as 2011, Kreol Rodrige was generally treated as a regional variety of Kreol Morisien rather than a language in its own right. It is now treated as autonomous. It acquired its own orthography document in late 2019, and its own dictionary, the Diksioner Kreol Rodrige, in prototype in December 2019 and in full in December 2021.

That shift is why you now see the umbrella term Kreol Repiblik Moris, covering Kreol Morisien and Kreol Rodrige together, and why the body regulating the language became the Akademi Kreol Repiblik Moris, announced in 2019. The updated orthography report published in May 2024 covers both.

Mauritian and Réunion

Here there is an actual scholarly dispute, which is unusual enough to be worth knowing about.

Réunion was settled before Mauritius, and one long-standing view holds that Réunion Creole fed into the formation of Mauritian. Philip Baker and Chris Corne are associated with the opposing position, that Réunionnais influence on Mauritian was minimal and that the two formed largely independently. The question is not settled, and the literature on it is worth reading directly rather than through summaries, including this one.

Either way, Réunion Creole is the least like Mauritian of the Indian Ocean group. It is generally described as closer to French in structure, which makes it easier going for a French speaker and less familiar to a Mauritian.

The other confusion: the language and the people

"Mauritian Creole" has a second, quite different meaning. Creole in Mauritius is also an ethnic designation, referring to Mauritians of largely African and Malagasy descent, one of the island's several communities. The Kreol population and the Kreol language are not the same thing, and they do not map onto each other: the language is spoken at home by the large majority of Mauritians of every background.

This trips up search results constantly, because English uses the same phrase for both. If you are reading about "Mauritian Creoles" in the plural, you are almost certainly reading about people rather than grammar.

A note on what to search for

Always include "Mauritian". Dropping it will hand you Haitian material nine times out of ten. If you want the language specifically, Kreol Morisien is the most reliable search term, because it is the name used by the Mauritian Ministry of Education, the school syllabus and the academic literature, and almost nothing else uses that phrase.
