The Aromanian language (Aromanian: limba armãneascã, limba armãnã, armãneashti, armãneashte, armãneashci, armãneashce or limba rrãmãneascã, limba rrãmãnã, rrãmãneshti), also known as Vlach or Macedo-Romanian, is an Eastern Romance language, similar to Megleno-Romanian, Istro-Romanian and Romanian, spoken in Southeastern Europe. Its speakers are called Aromanians or Vlachs (a broader term and an exonym in widespread use to define Romance communities in the Balkans).
Aromanian shares many features with modern Romanian, including similar morphology and syntax, as well as a large common vocabulary inherited from Latin. They are considered to have developed from Common Romanian, a common stage of all the Eastern Romance varieties. An important source of dissimilarity between Romanian and Aromanian is the adstratum languages (external influences); whereas Romanian has been influenced to a greater extent by the Slavic languages, Aromanian has been more influenced by Greek, with which it has been in close contact throughout its history.
