Abstract Asking first about how the lexical meaning manifests itself as we experience it in a communicative event, the author explores the background of the ways in which we are able to perceive the meaning of words in texts. One useful way of thinking about how recipients react to the words in utterances is in terms of behavioural and actional lexical meaning. The first refers to the understanding of meaning, the second corresponds to interpretations of words when the recipient does not succeed in the process of natural understanding of words. These terms lead to questions about the rationality of language. One aspect of this rationality is the function of the intentionalemergent mechanism that adjusts the interplay of automatic and deliberate use of language. This mechanism has its roots in the fundamental human nature: we are behaviouralactional beings. Pragmatic analysis sheds light on how hearers understand and interpret what they hear with regard to their conceptual knowledge associated with words.
