The official and common language is Dhivehi, an Indo-Aryan language closely related to the Sinhala language of Sri Lanka. The first known script used to write Dhivehi is the ''eveyla akuru'' script, which is found in the historical recording of kings (''raadhavalhi''). Later a script called ''dhives akuru'' was used for a long period. The present-day script is called Thaana and is written from right to left. Thaana is said to have been introduced by the reign of Mohamed Thakurufaanu.
