Dhivehi, the native Maldivian language, is distinct to the archipelago and can only be spoken there. In terms of language, this is an Indo-Aryan language that is primarily derived from the Sri Lankan language, Sinhala, with different vocabulary and grammar adopted from other civilisations that have frequented or exploited the islands as a base of operations. As a result of contributions from Urdu, Persian, Arabic, Dravidian, European languages (including French as well as Portuguese), and English throughout the years, Dhivehi has developed into the rich language that it is now. The reasoning as to why English is so extensively spoken in this archipelago is because it is the official language of instruction in the country's educational institutions. Despite the fact that the Dhivehi script is written on all the islands where it is used, the majority of signage in the area is in English.
