This paper presents selected issues related to the 18th century toponyms in the region of
Chełm. Manuscript sources report microtoponymic formations that display inconsistency in the implementation
of the then-contemporary standards of spelling and frequent alternations in the spelling
of the particular names. The causes need to be sought in language interferences, limited language
competence and the bilingualism of the authors. Searching for the appropriate classification of the
analysed toponyms, the author created his own classification, which is mostly based on modifications
of the existing proposals. This choice is dictated by the specificity and diversity of the microtoponymic
system under analysis. It is also evoked by the lack of a universally accepted and uniform
system of toponyms.
