Shtokavian or Štokavian (; , ) is the prestige dialect of the pluricentric Serbo-Croatian language, and the basis of its Bosnian, Croatian, Serbian, and Montenegrin standards. It is a part of the South Slavic dialect continuum. Its name comes from the form for the interrogatory pronoun for "what" in Western Shtokavian, što (it is šta in Eastern Shtokavian). This is in contrast to the Kajkavian and Chakavian dialects (kaj and ca also meaning "what").
