The article deals with selected aspects of Polish text linguistics research. It points to the diversity of defi nitions and the lack of clear criteria for the classifi cation of texts. There is also a lack of distinction between the text and the sentence or phrase, resulting from ambiguous features describing these terms. The article also indicates the variety of defi nitions of ‘coherence', ‘cohesion', ‘delimitation' etc., describing the text as a communication unit. On the basis of the anthropocentric theory of human languages the author presents the model of expression, which shows factors that infl uence the form and content of utterances, related to senders and recipients as well as a given situation/given circumstances. Linguistic expressions cannot be assigned a function or a communicative pragmatic view of the need to take account of linguistic and non-linguistic characteristics of senders and recipients of expressions and their ability to interpret these expressions. Each linguistic utterance is shaped according to the language skills and knowledge of the surrounding reality developed by the participants of the given communicative situation, and the analysis of the circumstances in which a given linguistic utterance is formed.
