There are two important differences between American English and British English with respect to main verb have. First, American English typically employs do-support in constructions such as Do you have any coffee? while traditional British English does not. Secondly, American English typically does not use have in expressions such as I took a shower whereas British Isles English does: I had a shower. In this article, we discuss the possibility that there is a connection between these two facts. We argue that the connection lies in the failure of have in North American English to acquire the full range of dynamic meanings that it has acquired in other varieties of English, and suggest language contact as one explanation for this phenomenon.
