Ante Starčević
In 1850, incited by Ljudevit Gaj, Starčević started working on the manuscript of Istarski razvod, a crucial Croatian document from 1325. He transcribed the text from the Glagolitic alphabet to the Latin alphabet, analyzed it and published it in 1852. In the foreword, young Starčević elaborated his linguistic ideas, pointing out that the mixture of all three Croatian dialects (Shtokavian, Chakavian) and Kajkavian) and the Krajina dialect is called the Croatian language, which Starčević considers from the perspective of its six hundred years of history. Starčević accepted the etymological orthography and used the ekavian form for his entire life, considering it the heir of the old Kajkavian. His language is a "synthetic" form of Croatian, never used before or after him, most similar to the Ozalj idiom of Petar Zrinski, whom he probably never read.
