The author studies ethnic stereotypes in the history of English from the perspective of Cognitive Linguistics. He views an ethnic stereotype as an idealised cognitive model (ICM) which consists of a cluster of metonymic submodels (such as BODY, CUISINE, NAME, etc.). Each submodel may trigger the formation of an attributive ethnonym, which ascribes some attribute to the target group. While such terms are mostly derogatory, context plays a crucial role in their perception. The analysis proper focuses on foodsemic ethnonyms (most of which activate the submodel of CUISINE). Out of 168 items, above 50% follow the or metonymy. Most examples come from Am.E., with Mexicans being the most frequently described target group.
