Developmental tendencies in the noun inflection variation in the Karviná vernacular

The work focuses on the varying forms of nouns in the common speech of the inhabitants of Karviná. Based on the previous literature on nominal declension in Silesian territory in conjunction with the native speaker's own experience, several varying morphological phenomena were selected for analysis, namely hard declension of soft noun patterns in the singular (muž/muža, moři/mořu, růže/růža) and unification of plural forms, especially in dative, locative and instrumental (dative to -am, locative to -ach, instrumental to -ami / -ama). Three data collection techniques were used for the research: a shorter sociolinguistic interview, which provided a general insight into the speech of selected speakers and served to find out the necessary demographic information; controlled oral elicitation, where the participants of the research were directed by prepared questions to the use of the investigated morphological phenomena; and an online questionnaire that provided information on conscious notions of the use of the studied phenomena, which will be confronted with information from the previous two techniques of data collection, interview and elicitation. The aim of this work is to describe a certain development of language in Karviná, based on a comparison of the younger generation (15-20 years) and older..
