Romanian is spoken by about 28 million people living mainly in Romania and Moldova (where it is referred to as Moldovan for political reasons). It is a member of the Eastern Romance language family. In ancient times, Romania was inhabited by the Dacian peoples who spoke the Dacian language, an Indo-European tongue, about which there remains very little knowledge. Many exclusively Romanian words found in all dialects of the language, or with an Albanian language cognate, are considered to have been inherited from Dacian. After Rome conquered the Dacian territory, it was made a Roman province where Vulgar Latin became the primary means of communication. As a result of its geographical isolation, the Romanian language was likely the first language that broke away from Latin and, until modern times, has not been influenced by other Romance languages. This has resulted in a grammar that is broadly similar to Latin, maintaining the neuter gender and declensions unlike any of the other Romance languages.
