Russian language varieties and styles

Surzhyk (Ukrainian and Russian: , , ) is a mixture between Ukrainian and Russian languages, used in certain regions of Ukraine and the neighboring regions of Russia and Moldova. The phenomenon of surzhyk is commonly interpreted as an application of Russian-language words and idioms in combination with Ukrainian speech, which makes it essentially a heavily Russified version of colloquial Ukrainian, although the opposite process can also take place.

Trasianka or trasyanka (, ) is a mixed form of speech in which Belarusian and Russian elements and structures are combined arbitrarily. Due to the negative connotation of the word trasianka it has been suggested that in the linguistic debate the term "Belarusian-Russian mixed speech" should be used.
