Bosnian (Bosnian) and Croatian (Croatian) 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.
Hrvatski · Standard Croatian
The Zagreb-based standard of Croatian, built on a Štokavian basis. Distinguished from Serbian by lexical preferences and a strict Latin-script orthography.
Start with Bosnian or Croatian based on the community, country, or media you expect to use most.
