text: Chakavian literary language Since Chakavian was the first South Slavic dialect to emerge from the Church Slavic matrix, both literacy and literature in this dialect abound with numerous texts - from legal and liturgical to literary: lyric and epic poetry, drama, novel in verses, as well as philological works that contain Chakavian vocabulary. Chakavian idiom was de facto the main public and official language in medieval Croatia up to the 16th century. Chakavian literature uses many words of Latin, Dalmatian, and Italian origin due to the millennial long contacts with these languages. When compared different epochs with different status of Chakavian dialect (i.e. Croatian language), such words became more widespread in local speeches in the last few centuries, creating various Chakavian-Italian hybrid words. There also exist significant differences in the lexicon between Northwestern and Southeastern groups of sub-dialects, showing there is no unique Chakavian language system.
  Comparison of earliest texts in Croatia shows that the Slavic language changed until the 11th century and was not exclusively of Chakavian idiom, and Chakavian features started to be widespread only since 12th-13th century when can be dated formation of Chakavian dialect. Monuments of literacy began to appear in the 11th and 12th centuries, and artistic literature in the 15th. There were two zones of Chakavian, northern and southern (both mainly along the Adriatic coast and islands, with centres like Senj, Zadar, Split, Hvar, Korčula). Many of these used Chakavian, and up to the 17th century the texts were written in both Glagolitic, Bosnian Cyrillic and Latin alphabet.
  The Chakavian language by far surpassed the position of a simple vernacular dialect and strongly influenced other Croatian literary dialects, particularly Western Shtokavian: the first Shtokavian texts such as the Vatican Croatian Prayer Book, dated to 1400, exhibit numerous literary Chakavianisms. The early Shtokavian literary and philological output, mainly from Dubrovnik (1500–1600) up to Džore Držić, was essentially a mixed Shtokavian–Chakavian idiom.
