Jak liczą Polacy – lingwakulturowe aspekty gramatyki opisowej i historycznej liczebnika

The article is dedicated to the issue of how to teach the grammar of numerals to foreigners. The article exposes the problem of a dual way of expressing plurality in sentence structures. The author provides the grammatical explanation of the issue provided, in which the nominality of the numerals (lower or higher than 5) determines the nominative or genitive sentence structure. Together with the neurolinguistics interpretation of this mechanism, the text provides also linguacultural reflections which constitute its essence. An anthropomethric explanation and the history of the formation of the linguistic principle are illustrated. Additionally, the text is a particular proposal of an interdisciplinary narrative in teaching the Polish language.
