In modern times, many Bulgarians speak a Southern Slavic language which has been deeply influenced by Medieval and Modern Greek, as well as - though in a lesser extent - by Osmanli Turkish. It has many traits in common with Slovenian and Croatoserbian, with which it can sometimes be mutually intelligible, although this is not true of its intelligibility with Western and Eastern Slavic languages.
