ABSTRACT
This chapter provides evidence of a number of forms that appear to result from accommodation between Dialect and SF. In the first, variable acquisition, new forms are acquired that compete with the old ones in the repertoire, so that speakers use them variably, with the frequencies changing over time. A second form is lexical diffusion, in which speakers acquire a new feature, but not in the full range of lexical items in which it can occur, modifying some before others. A third consequence is the creation of interdialect forms, which are intermediate between the original and target dialects but present in neither: these may include phonetically ‘fudged’ forms, intermediate forms, hypercorrections, and hyperdialectalisms. Incomplete accommodation may result in the creation of forms that are phonetically intermediate between those of the original and target dialects.
