The article hereunder presents the language analysis of a charter from the 17th century titled “Wilkierz dla wsi klasztoru Panny Marji w Kartuzach” published by Stanisław Kutrzeba and Alfons Mańkowski in 1938 in Archiwum Komisji Prawniczej, volume 11. The text of an unknown scrivener was written in New High German in the Silesian dialect, what can be proved on the basis of the way of the notation in the law. The author introduces the results of his analysis showing the stage of the development of the consonant system with the appropriate examples.
