<!doctype html public «-//w3c//dtd html 4.0 transitional//en»> http-equiv=content-type> This study seeks to develop a foundation for a theory of meaning that views linguistic innovation and discursive dynamics as the normal state of affairs. It integrates systems and behavioral theory, identifying discourses as the loci of change in linguistic meaning. An analysis of multi-code metaphors makes plausible the discursive sensitivity of images in advertisements and leads to a proposal for a multicodal expansion of discourse analysis.
