Interrogative sentences in Bosnian grammar are sentences that ask a question and require an answer. They typically start with an interrogative word or particle such as “šta” (what), “koji” (which), “kako” (how), “kada” (when), “zašto” (why), “čiji” (whose), and “gdje” (where). The word order in Bosnian interrogative sentences is often flexible, and verbs usually come second in the sentence, preceded by the interrogative word or particle.
