Name
In the Bosnian, Croatian and Serbian languages, Republika Srpska means "Serb Republic". The second word is a nominalized adjective derived by adding the suffix -ska to srb-, the root of the noun Srbin, meaning Serb. The -ps- sequence rather than -bs- is a result of voicing assimilation. Although the name Republika Srpska is sometimes glossed as Serb Republic or Bosnian Serb Republic (Serbian: Republika Bosanskih Srba / Република Босанских Срба), and the government of Republika Srpska uses the semi-Anglicized term Republic of Srpska in English translations of official documents, western news sources such as the BBC,The New York Times, and The Guardian generally refer to the entity as the Republika Srpska.
