This book presents an ongoing debate in cognitive linguistics about the modelling of prepositional polysemy, known as "the story of over." Additionally, it discusses a Polish counterpart - "the story of za(-)" (a preposition and a verbal prefix). Its further aim is to reveal a deep divergence of perspectives between the cognitive and hermeneutical approaches to the meaning of words. The argument could be summarised as follows: the issue of the representation of lexical senses (available out of context) presupposes the issue of distinct meanings of words in communal use, which in turn presupposes the question of the transformative power of words (in linguistics, articulated by Humboldt as energeia). In short, the book proposes to complement a post hoc static cognitive approach with a dynamic "expressive" one.
