Termin substytucja w ujęciu fonodydaktycznym i logopedycznym. Analiza porównawcza

The article examines the term substitution by focusing on the ways in which it has been defined and/or applied in the context of pronunciation errors, especially by two different scientific disciplines: Polish language teaching (more precisely: phonodidactics) and speech therapy. Interestingly, despite the fact that the term refers to the same or similar object of study, it is not necessarily used with the same meaning. The paper opens with a review of definitions from general and specialized dictionaries along with a formulation of the concept. The study was carried out according to a socio-terminology approach, taking into account the contextual updating of meanings, observed polysemy and synonymy, as well as a socio-cognitive approach, checking the popularity of using the term and ways of understanding it in a specific context. Both the general term and the term specified by a modifier (e.g., phonetic, phonological substitution) have been described and exemplified thanks to the database of texts from both disciplines to show similarities and differences resulting from the adopted perspectives or goals (research or practical ones) that the representatives of each fi eld of study set for themselves. The analysis made it possible to observe the process of determinologization, as well as the co-occurrence of several different concepts in both disciplines, referenced by the same terms. The study fi ts into the descriptivist trend, but it aspires to be a point in the discussion about the precise formulation of descriptions, especially in disciplines that share interests with other fitelds of science.
