their language. History Madagascar was first settled by Austronesian peoples from Maritime Southeast Asia from the Sunda Islands (Malay archipelago). As for their route, one possibility is that the Indonesian Austronesian came directly across the Indian Ocean from Java to Madagascar. It is likely that they went through the Maldives, where evidence of old Indonesian boat design and fishing technology persists until the present. The migrations continued along the first millennium, as confirmed by linguistic researchers who showed the close relationship between the Malagasy language and Old Malay and Old Javanese languages of this period. The Malagasy language originates from the Southeast Barito languages, and the Ma'anyan language is its closest relative, with numerous Malay and Javanese loanwords. It is known that Ma'anyan people were brought as labourers and slaves by Malay and Javanese people in their trading fleets, which reached Madagascar by ca. 50–500 AD. Later, c. 1000, the original Austronesian settlers mixed with Bantus and Arabs, amongst others. There is evidence that the predecessors of the Malagasy dialects first arrived in the southern stretch of the east coast of Madagascar. Malagasy has a tradition of oratory arts and poetic histories and legends. The most well-known is the national epic, Ibonia, about a Malagasy folk hero of the same name. Geographic distribution Malagasy is the principal language spoken on the island of Madagascar. It is also spoken by Malagasy communities on neighboring Indian Ocean islands such as Réunion, Mayotte and Mauritius. Expatriate Malagasy communities speaking the language also exist in Europe and North America. Legal status The Merina dialect of Malagasy is considered the national language of Madagascar. It is one of two official languages alongside French in the 2010 constitution put in place the Fourth Republic. Previously, under the 2007 constitution, Malagasy was one of three official languages alongside French and English. Malagasy is the language of instruction in all public schools through grade five for all subjects, and remains the language of instruction through high school for the subjects of history and Malagasy language. Dialects There are two principal dialects of Malagasy; Eastern (including Merina) and Western (including Sakalava), with the isogloss running down the spine of the island, the south being western, and the central plateau and much of the north (apart from the very tip) being eastern. Ethnologue encodes 12 variants of Malagasy as distinct languages. They have about a 70% similarity in lexicon with
