The Slovene Littoral, or simply Littoral, is one of the traditional regions of Slovenia. The littoral in its name – for a coastal-adjacent area – recalls the former Austrian Littoral, the Habsburg possessions on the upper Adriatic coast, of which the Slovene Littoral was part. Today, the Littoral is often associated with the Slovenian ethnic territory that, in the first half of the 20th century, found itself in Italy to the west of the Rapallo Border, which separated a quarter of Slovenes from the rest of the nation, and was strongly influenced by Italian fascism.

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.
