This book analyses the occurrence of synonymy in the texts of academic prose and fiction. The topic of synonymy has been in the centre of attention for a long time and it still deserves much attention. The aim of this thesis is to approach to the topic from a different perspective. Theoretical part describes the theoretical background of synonymy from the upper layers of the system of language. These theories are used as analytical tool in analysing the collected samples with the focus on similarities and differences in connotation of pairs of synonyms. This work should particularly contribute to study of partial synonymy and the components of associative meaning that vary in dependence on functional style. This work should also marginally refer to the topic of absolute synonymy. The frequency of the components of associative meaning and findings are described in the conclusion of the thesis. ukryj opis
