The paper presents a brief summary of the multi-level interdisciplinary research on Englishmen’s ethnic stereotypes about the Dutch and the ways they manifest themselves in the English language. Unconventionally, the national stereotype is investigated as a subject of Cognitive Linguistics. As a result, the term “conceptual model” is proposed as an equivalent to “conceptual metaphor”, and two conceptual models verbally represented by the ethnonym “Dutch” and phraseological units with this component are described. A literature review examines if the identified conceptual models are supported in literary discourse, then the usage of the key lexis is analyzed meticulously for the same purpose. The last part of the paper suggests the results of the experiment held to verify if the stereotypical perceptions of the Dutch are maintained by people in contemporary Great Britain. The results indicate that language plays a significant role in stereotype formation and maintenance.
