Internal migration to the capital Skopje in the 1950s and 1960s led to the development of a new, urban slang where newly arrived people attempted to incorporate elements of the Skopje-Veles dialect into their own speech, often confusing local elements with those from Serbo-Croatian. Language contact with Serbo-Croatian, then a more prestigious language in SFR Yugoslavia, also reached its height during this period. This variety has been described as a "creolized form of Serbian" (cf. also Surzhyk in Ukraine, Trasianka in Belarus) and is distinct from the 'authentic' Skopje-Veles dialect.
