Old Dhivehi is the earliest attested form of the Maldivian language, with records found in the Loamaafaanu from the 12th and 13th centuries CE, as well as various Buddhist texts dating back to the 6th century CE. It is the ancestral form that evolved into the modern northern dialect of the Dhivehi language. Old dhivehi belongs to Indo-Aryan branch of the wider Indo-European language family.
No endonym for the language is known. However the language may have been called "Dhuvesi" or "Dhivesi" meaning "Islander", which has evolved into the endonym for the modern language.
Old Dhivehi descends through Proto Dhivehi-Sinhala or Elu spoken in 3rd century BCE. Around 1st century BCE, the unattested Proto-Dhivehi, the direct ancestor to all Maldivian dialects, started to separate from Elu prakrit. Proto-Dhivehi came to be influenced by subcontinental Middle Indo-Aryan dialects and Dravidian languages.
Vowel inventory of Old Dhivehi is mostly identical to that of modern dhivehi. Like Sinhala and Dravidian and unlike most Indo-Aryan languages, spoken Old Dhivehi distinguished between long and short forms of [, ] and [, ]. However these were not distinguished in writing.
