The Illyrian movement was a pan-South-Slavic cultural and political campaign with roots in the early modern period, and revived by a group of young Croatian intellectuals during the first half of the 19th century, around the years of 1835–1863. This movement aimed to create a Croatian national establishment in Austria-Hungary through linguistic and ethnic unity, and through it lay the foundation for cultural and linguistic unification of all South Slavs under the revived umbrella term Illyrian.

Slovene or Slovenian is a Western member of South Slavic languages, which belong to the Balto-Slavic branch of the Indo-European language family. Most of its 2.5 million speakers are the inhabitants of Slovenia, majority of them ethnic Slovenes. As Slovenia is part of the European Union, Slovene is also one of its 24 official and working languages. Its syntax is highly fusional and characterized by dual grammatical number. Two accentual norms are used. Its flexible word order is often adjusted for emphasis or stylistic reasons, although basically it is a SVO language. It has a T–V distinction: the use of the V-form demonstrates a respectful attitude towards superiors and the elderly, while it can be sidestepped through the passive form.
