Romanian is a Romance language, belonging to the Italic branch of the Indo-European language family, having much in common with languages such as French, Italian and Spanish.
However, the languages closest to Romanian are the other Eastern Romance languages, spoken south of Danube: Aromanian/Macedo-Romanian, Megleno-Romanian and Istro-Romanian, which are sometimes classified as dialects of Romanian. An alternate name for Romanian used by linguists to disambiguate with the other Eastern Romance languages is "Daco-Romanian", referring to the area where it is spoken (which corresponds roughly to the onetime Roman province of Dacia).
The Romanian variety spoken in Moldova has been named Moldovan language by the Soviet and later Moldovan authorities, but linguists do not recognize it as a different language.
