Expansion

An Item changes its physical size. The Size_change of an Item may be explicitly indicated or characterized in terms of Initial_size and/or Result_size. In the default case, expansion is along all dimensions, but sometimes the Dimension of expansion is incorporated or made explicit. This frame does not specify whether the Item gains mass or substance along with the change in size, and thus includes words that specify an increase in substance (grow.v) along with those that deny an increase in substance (stretch.v) and those that are unspecified (expand.v). The pile of leaves had shrunk by about half after the first haul. The jeans stretched a little.
