They speak Montenegrin in Montenegro, and several closely related languages are also in official use.

Main answer

  • The official language of Montenegro is Montenegrin.
  • Other languages in official use are Serbian, Bosnian, Albanian and Croatian.
  • These languages are very similar; Montenegrin, Serbian, Bosnian and Croatian are mutually intelligible varieties of the same South Slavic language continuum.

So if you learn some basic Montenegrin (or Serbian/Bosnian/Croatian), you can generally communicate across the whole region.
