Slavonic-Serbian
Slavonic-Serbian (славяносербскій, slavjanoserbskij), also known as Slavo-Serbian or Slaveno-Serbian (славено-сербскiй, slaveno-serbskij; Serbian: славеносрпски, slavenosrpski), was a literary language used by the Serbs in the Habsburg Empire, mostly in what is now Vojvodina, from the mid-18th century to the first decades of the 19th century, falling into obscurity by the 1870s. It was a linguistic blend of Church Slavonic of the Russian recension, vernacular Serbian (Shtokavian dialect), and Church Slavonic of the Serbian recension, with varying sources and differing attempts at standardisation.
