Serbian Cyrillic alphabet
The Serbian Cyrillic alphabet (Serbian: Српска ћирилица / Srpska ćirilica, IPA: [sr̩̂pskaː t͡ɕirǐlitsa]), also known as the Serbian script (Српско писмо / Srpsko pismo, Serbian pronunciation: [sr̩̂psko pǐːsmo]), is a standardized variation of the Cyrillic script used to write Serbo-Croatian. It is one of the two official scripts of the modern standard Serbian, Montenegrin and Bosnian, the other being Gaj's Latin alphabet.
