The applicability of Vantage Theory (VT), a model of (colour) categorization, to linguistic data largely depends on the modifications and adaptations of the model for the purpose. An attempt to do so proposed here, called Extended Vantage Theory (EVT), slightly reformulates the VT conception of vantage by capitalizing on some of the entailments of specific vantage levels, namely the three types of viewing: non-discriminatory, analytic and synthetic. It nevertheless maintains the fundamental mechanism of vantage construction, i.e. selective emphases to similarity or difference on the part of the conceptualizer. The extended model is applied to an analysis of nominal modification, especially the use of articles, in two English translations of Polish literary prose. (Contains 2 tables and 9 figures.)
