Bosnian (Bosnian) and Serbian (Serbian) are two of the four national standards of the Štokavian South Slavic language commonly referred to as BCMS (Bosnian–Croatian–Montenegrin–Serbian). Everyday speech is largely mutually intelligible; the standards differ in orthography, lexical preferences, and official status.
Bosanski
The Sarajevo-based standard of Bosnian. A Štokavian-based BCMS standard, distinguished by retention of Turkish, Arabic, and Persian loanwords from Ottoman rule and the use of both Latin and Cyrillic scripts.
Srpski · Standard Serbian
The Belgrade-based standard of Serbian. Part of the Štokavian dialect continuum that underlies all four BCMS national standards (Bosnian, Croatian, Montenegrin, Serbian); written in both Cyrillic and Latin scripts.
