The examples in question appear in feminine nouns (singular, instrumental case) ended with -a and they were considered as non-authentic by other researchers. The authoress of the article presents examples found in contemporary dialectal texts from the region of the old north-eastern borderland. They confirm that forms of instrumental that end with -a are not neologisms or potential forms but they reflect real phenomenon observed in Polis language of this region.
