Abstract
The aim of the article is to analyze the functioning of Cieszyn dialects on
the Internet. On the one hand, we want to describe the functions that this code fulfills,
both in primary and secondary use, and to provide a general formal analysis of dialectal
statements and statements with different number of dialectal elements, on the other. The dialectal texts and the texts with dialectal elements show a wide variety, both in terms of functionality and form. These are both written texts strictly edited and texts formulated ad hoc, sometimes even spontaneously. At the same time, due to the relatively high anonymity of spontaneous statements, they can naturally reveal the real knowledge and functional use of this code by different users.
