Serbians
The term Serbians in English is a polysemic word, with two distinctive meanings, derived from morphological differences: In English, the use of term "Serbians" depends on the context, with demonymic use being more common, but not exclusive. Demonymic use. The term "Serbians" is used in English as a demonym for all citizens of Serbia, regardless of their ethnic, linguistic, religious or other cultural distinctions. In Serbian, however, the term "Srbijanci" () is also used for ethnic Serbs from Serbia, or in a narrower sense, Serbs from Central Serbia (Serbia proper). The term thus excludes ethnic Serbs in the neighboring countries , such as Bosnia and Herzegovina, Croatia, Montenegro and North Macedonia, for which the common term "Srbin" () is used. In English, the two are commonly used interchangeably, with the term "Serbians" sometimes applied to ethnic Serbs outside Serbia (such as "Bosnian Serbians" for Bosnian Serbs). Likewise, the term "Serbs" has been erroneously applied to all citizens of Serbia regardless of their ethnicity. The term and usage of "Srbijanci" is controversial in Serbian-speaking areas. In Croatian usage, while "Srbi" is the term for ethnic Serbs, including Serbs of Croatia, "Srbijanci" are Serbs specifically from Serbia, but because no such distinctions exist  for other nations, it is inconsistently applied and the main meaning is to indicate something specific to citizens of Serbia as opposed to ethnicity. The term is used in the province of Vojvodina. In response to Tomislav Nikolić using the term "Bosanac" for Serbs of Bosnia and Herzegovina, Belgrade linguist Ivan Klajn said that this type of demonym and distinction between ethnicity and nationality are only found in Bosnia and Herzegovina and Serbia as opposed to other European countries, even other former Yugoslav republics. The 1852 "Srpski rječnik" includes the following: A popular Serbian folk song contains a chorus " ..."jelek  (vest), anterija" (short vest), and "opanci" (traditional moccasins), is how you recognize a "Srbijanac" (Serbian)...", describing the Serbian folk costume. Variant terms like "Old Serbians" () and "Southern Serbians" () were used as designations for populations from historical regions of Old Serbia, and Vardar Macedonia respectively.
