Chakavian
Chakavian in its actual use is the least spoken Serbo-Croatian dialect, being spoken only by 12% Croats. It is now mostly reduced in southwestern Croatia along the eastern Adriatic: Adriatic islands, and sporadically in the mainland coast, with rare inland enclaves up to central Croatia, and minor enclaves in Austria and Montenegro. All areas of old contacts with Romance languages.
Dialects of Serbo-Croatian
Kajkavian literary language gradually fell into disuse since Croatian National Revival, ca. 1830–1850, when leaders of the Croatian National Unification Movement (the majority of them being Kajkavian native speakers themselves) adopted the most widespread and developed Serbo-Croatian Shtokavian literary language as the basis for the Croatian standard language. However, after a period of lethargy, the 20th century has witnessed new flourishing of literature in Kajkavian dialect – this time as Croatian dialectal poetry, main authors being Antun Gustav Matoš, Miroslav Krleža, Ivan Goran Kovačić, Dragutin Domjanić, Nikola Pavić etc. Nowadays, Kajkavian lexical treasure is being published by the Croatian Academy of Sciences and Arts in "Rječnik hrvatskoga kajkavskoga književnoga jezika"/"Dictionary of the Croatian Kajkavian Literary Language", 8 volumes (1999).
