The phenomenon under discussion is an example of a grammatical change that can be explained by refunctionalization, and as such, can be understood as the acquisition of a new meaning by an ‘endangered’ grammatical construction, which is reassigned to express another value. Refunctionalization involves the development of a new function (in this case a syntactic-semantic one). When an item loses its function, or is marginal within a system, it can be lost (as happens with the construction under study in Standard Spanish), it can be ‘saved’ as a marginal element (as in some areas of American Spanish varieties) or it can be reused for other purposes (as in the Central American Spanish varieties). The latter case presents new discursive values. Hence, this construction should be understood as an example of reusing grammatical functionally opaque material for new purposes.
