Aromanian is an Eastern Romance language spoken in Greece, Albania, Macedonia, Romania, Bulgaria and Serbia by about 300,000 people. Aromanian is closely related to Romanian, though contains more vocabulary of Greek origin, while Romanian has absorbed a lot of vocabulary from Slavic languages and Hungarian.
The Aromanians are known by different names, including Vlasi (Macedonian and Serbian), Vlahi (Greek), Ulahlar (Turkish), Vllehë or Çobani (Albanian), Vlachs (English), Wlachen or Walachen (German) and Valaques (French). The Serbs call the Aromanians Tsintsari, and they are known as Macedo-Romãni by the Romanians. They call themselves Armãnji, and their language armãneashti or limbã armãneascã.
Aromanian has some official status in the Republic of Macedonia and is taught in some primary schools there as an optional subject. Aromanian speakers in Macedonia have the right to use Aromanian in court, and since 2006 Aromanian has been the second official language (after Macedonian) in the city of Kruševo (Crushuva).
