Romanian (obsolete spellings: Rumanian or Roumanian; autonym: limba română , or românește, ) is the official and main language of Romania and the Republic of Moldova. As a minority language it is spoken by stable communities in the countries surrounding Romania (Bulgaria, Hungary, Serbia, and Ukraine), and by the large Romanian diaspora. In total, it is spoken by 28–29 million people as an L1+L2 language, of whom 24 million are native speakers. In Europe, Romanian is rated as a medium level language, occupying the 10th position among 37 official languages. Romanian is part of the Eastern Romance sub-branch of Romance languages, a linguistic group that evolved from several dialects of Vulgar Latin which separated from the Western Romance languages in the course of the period from the 5th to the 8th centuries. To distinguish it within the Eastern Romance languages, in comparative linguistics it is called Daco-Romanian as opposed to its closest relatives, Aromanian, Megleno-Romanian, and Istro-Romanian. Romanian is also known as Moldovan in Moldova, although the Constitutional Court of Moldova ruled in 2013 that "the official language of Moldova is Romanian". Overview The history of the Romanian language started in the Roman provinces north of the Jireček Line in Classical antiquity, over a large area . Between the 6th and 8th century, following the accumulated tendencies inherited from the vernacular spoken in this large area and, to a much smaller degree, the influences from native dialects, and in the context of a lessened power of the Roman central authority the language evolved into Common Romanian. This proto-language then came into close contact with the Slavic languages and subsequently divided into Aromanian, Megleno-Romanian, Istro-Romanian, and Daco-Romanian. Due to limited attestation between the 6th and 16th century, entire stages from its history are re-constructed by researchers, often with proposed relative chronologies and loose limits. As a separate entity, starting from the 12th or 13th century, Romanian was superseded in official documents and religious texts by Old Church Slavonic, a language that had a similar role to Medieval Latin in Western Europe. The oldest dated text in Romanian is a letter written in 1521 with Cyrillic letters, and until late 18th century, including during the development of printing, the same alphabet was used. The period after 1780, starting with the writing of its first grammar books, represents the modern age of the language - a phase when the Latin alphabet became official,
