Functional logical semiotics of natural language

In the first part of my paper I briefly present Jerzy Pelc's functional approach to logical semiotics of natural language. This approach focuses on the use of natural language expressions and on its dependence on context and conversational situation. One of the important goals of this analysis is to appreciate the role of sentences in natural language and stress that it is by means of sentences that language fulfills its main roles. However, for Pelc almost any expression can be used as a sentence, despite not being a grammatical sentence. In the second part I try to place Pelc's standpoint within the framework of contemporary semantic minimalism - contextualism debate. I pay special attention to his treatment of subsentential expressions used to express propositions and argue that his view belongs to pragmatics-oriented approaches to subsentential speech acts.
