The article presents the changes of phonetics in the contemporary Lubawa dialect which took place over the period of fifty years in a new local dialect of the town. The lexical items included in the monograph The Vocabulary of Warmia and Mazuria were compared to a dialect lexicon collected in Lubawa and its vicinity, also in Rumian, a village that once used to belong to the demesnes of Lubawa. The lexis also stems from The Stories by Klimek from Dybzak by B. J. Standara. The informers belonged to the oldest generation. The vocabulary domains pertaining to breeding and farming have only survived to an inconsiderable extent.
