Malagasy is the principal language spoken in Madagascar, with about 25 million native speakers as of 2015.
It is one of the two official languages of Madagascar, alongside French125.
The standard variety, called Official Malagasy, is based on the Merina dialect spoken in the central highlands around the capital Antananarivo5.
Malagasy is also spoken by Malagasy communities on neighboring islands such as Réunion, Mayotte, and Mauritius, as well as expatriate communities in Europe and North America45.
Malagasy is an Austronesian language, specifically part of the Malayo-Polynesian branch, and is the westernmost Austronesian language5.
It is closely related to the Ma’anyan language of Borneo and contains many loanwords from Malay, Javanese, Bantu, Arabic, and Sanskrit, reflecting historical migrations and trade5.
The language has twelve dialects divided into Eastern and Western groups, with the Merina dialect forming the basis of the standard language5.
