Parallel forms and usage of ablative case in Hungarian and Turkic languages There are several similar phenomena present in the languages of both Uralic and Altaic language families due to the vehement, intensive and lasting contacts at different times of peoples speaking those languages in the past. The way they express three different directions (with the help of dative, locative, ablative cases) is only one of them. There are studi es dealing with the mutual influences as well as with convergent developments. We are aware of loanwords present on both sides of the language groups, whereas little has been written about borrowed suffixes. And yet endings are considered to be the most stable part of any language. We want to stress the importance of the parallel forms and the usage of the ablative case +nAn (and its variant +nAt in Hungarian). We suppose it to be a case marker in Hungarian borrowed most probably from Kipchak (among others Cumanian) languages.
