In the paper I outline the general conception of meaning which is based on understanding it as a creation determined through the way of using linguistic expressions. The concept of meaning is based on ideas deriving from L. Wittgenstein [1953] and independently from K. Ajdukiewicz ([1931], [1934]), and it is connected with the so called functional approach to analysis of natural language – the notion introduced by Jerzy Pelc ([1971, 1979]). This is marked by taking into consideration the manner of use expressions. Following Pelc, we distinguish two understandings of this statement: in the first of them, the manner of use concerns only expression-tokens (material signs); in the other – the manner of Use (usage) characterizes the meaning of expression-types (classes of expression-tokens). This manner is somehow built into the meaning. The relation of use, concerning all the relations of physical object-based reference of expression-tokens made by users of language, will be a primitive notion of the theory outlined here. The relation Use, usage is, on the other hand, a relation defined by means of the relation of use and applied by users of the language for expression-types. The meaning the expression-type e is defined as the equivalence class of the relation possessing same manner of Use (usage) of types determined by type e. It may intuitively be understood as a common property of all expression-types possessing the same manner of Use (usage) as the expression e.
