The official languages of the Comoros are Comorian, French and Arabic, as recognized under its 2001 constitution. Although each language holds equal recognition under the constitution, language use varies across Comorian society. Unofficial minority languages such as Malagasy and Swahili are also present on the island with limited usage. According to Harriet Joseph Ottenheimer, a professor of anthropology at Kansas State university, the linguistic diversity of the Comoros is the result of its rich history as part of the Indian maritime trade routes and its periods of Malagasy and French colonial rule.
