* Bosnian: This is the official language of Bosnia and Herzegovina and is spoken by the majority of Bosniaks.
* Serbian: Serbian is closely related to Bosnian and is spoken by a significant minority of Bosnians.
* Croatian: Croatian is also closely related to Bosnian and is spoken by another significant minority of Bosnians.
It's important to note that these three languages are essentially dialects of the same language, often referred to as Serbo-Croatian. While there are some differences in pronunciation, vocabulary, and grammar, speakers of these languages can generally understand each other.
In addition to these three languages, many Bosnians may also be fluent in English or other foreign languages depending on their education and experiences.
