Anymore is regularly used in negative , interrogative , and conditional contexts and in certain positive constructions . In many regions of the United States the use of anymore in sense 2 is quite common in positive constructions, especially in speech . The positive use appears to have been of Midland origin, but it is now reported to be widespread in all speech areas of the United States except New England.
