Eastern Romance languages
Map of Balkans with regions currently significantly inhabited by Romanians/Vlachs highlighted
The Eastern Romance languages in their narrow conception, sometimes known as the Vlach languages, are a group of Romance languages that developed in Southeastern Europe from the local eastern variant of Vulgar Latin. Some classifications include the Italo-Dalmatian languages; when Italian is classified as Western Romance, Dalmatian generally remains in Eastern. This article will be concerned with Eastern Romance in the narrow sense, without Italian.
Several hundred years after the Roman Empire's dominance of the region, the local form of Vulgar Latin developed into Proto-Romanian, a language which had most of the features of modern Romanian. Probably due to foreign invasions (see Romania in the Dark Ages) and the migration of Vlach shepherds (see Vlachs in Wallachia), between 800 AD and 1200 AD Proto-Romanian split into four separate languages:
- Daco-Romanian (called Romanian in Romania and most countries, but officially known as Vlach in Serbia and sometimes as Moldovan in Moldova);
- Aromanian (called Vlachika in Greece, officially known as Vlas in Serbia, and also as Aroman);
- Megleno-Romanian (also known as Moglenit in former Yugoslavia and in Bulgaria, or Megleniotika in Greece) ;
- Istro-Romanian (also known as Istrian in Italy, and as Ćićiski or Ćiribirski in former Yugoslavia).

The Proto-Romanian branch was one of the earliest language groups to be isolated from the larger Latin family. As such, the languages contain a few words that were replaced with Germanic borrowings in Western Romance languages, for example, the word for white is derived from Latin "albus" instead of Germanic "blank".
They also share a few sound changes with the western Romance languages: some with Italian, such as [kl] > [kj] (Lat. clarus > Rom. chiar, Ital. chiaro) and also a few with Dalmatian, such as [gn] > [mn] (Lat. cognatus > Rom. cumnat, Dalm. comnut). However, most of them are original, see: Latin to Romanian sound changes.
The languages that are part of this group have some features that differentiate them from the other Romance languages, notable being the grammatical features shared within the Balkan language area as well as some semantic peculiarities, such as lume ("world") being derived from Latin lumen ("light"), inimă ("heart") being derived from Latin anima ("soul"), etc.
