These discussions fall into the stream of studies on pragmatic aspects of linguistic communication, are connected with the research on family language/style, familect, privacy discourse. Based on an analysis of the texts by and about the Kossak family (letters, notes, memoirs, biographical stories), this paper outlines selected aspects of interfamily communication: favourite expressions and humorous stylisation devices. The analysis has permitted the observation that the Kossak family’s statements are abundant with (positive and negative) linguistic expression devices, contain encrypted elements, and are characterised by high creativity. The addressee’s astonishment and amusement seems to be the main intention of a majority of the analysed linguistic behaviours.
