The author classifies researchers in the field of literature studies, historians and popular science journalists as non-specialists in diachronic language studies. Having done so, the author analyses texts written by these authors as regards their views on historical studies in Slavic linguistics, historical grammar, history of Polish, onomastics, etymology and history of proper names. The list of analysed researchers and writers includes: Jarosław Marek Rymkiewicz, Krzysztof Masłoń, Leszek Szaruga (Witold Wirpsza), Jerzy Krasucki and Agnieszka Krzemińska. The paper ends with an appeal addressed to experts in diachronic language studies that they follow such outstanding Polish researchers and linguistic knowledge promoters as Jan Michał Rozwadowski, Kazimierz Nitsch, Stanisaaw Urbańczyk or Marian Kucała in popularizing diachronic language studies among the wide public.
