One well-known difference between British and American English concerns the verb prevent. In both varieties, the verb is commonly found in constructions with NP from -ing, as in […] the extreme temperature of the cold tenderises the flesh and prevents it from becoming tough (NOW Corpus 2010), and in British English it is also commonly found in corresponding constructions lacking the preposition from, as in Morgan […] fastened a belt around his wrists to prevent him saving himself (NOW Corpus 2011). There are major unresolved issues relating to the two types of constructions illustrated. One question is whether the constructions involve object control or a Raising rule. One novel idea proposed is that an ACC -ing analysis should be available for the pattern without from. The British and American segments of the NOW corpus offer good sources of data, which have not been used in earlier work on prevent.
