Demographics of Croatia
Croatian replaced Latin as the official language of the Croatian government in 1847. The Croatian lect is generally viewed as one of the three standard varieties of the Shtokavian dialect of Serbo-Croatian, a South Slavic language. Croatian is written using the Latin alphabet and there are three major dialects spoken on the territory of Croatia, with the Shtokavian idiom used as the literary standard. The Chakavian and Kajkavian dialects are distinguished by their lexicon, phonology, and syntax.
Bartol Kašić
In almost 200 pages and two parts ("books"), he provided the basic information on the Croatian language and explained the Croatian morphology in great detail. The language is basically Shtokavian with many Chakavian elements, mixing older and newer forms. For unknown reasons, the grammar was not accompanied by a dictionary, as was the practice with Jesuit dictionaries and grammars of Croatian.
