Antecedent-contained deletion

Antecedent-contained deletion (ACD), also called antecedent-contained ellipsis, is a phenomenon found in contexts containing verb phrase ellipsis and a quantifier. The ellipsis appears to be contained inside its antecedent, which should result in an infinite regress and thus ungrammaticality. The problem arises in phrase structure grammars that take the constituent to be the fundamental unit of syntactic analysis. It does not arise if the catena is taken to be the fundamental unit. The catena is associated with dependency grammars (DGs).

To understand the issue involved, it is necessary to understand how VP-ellipsis works. Consider the following examples, where the expected, but elided, VP is represented with a smaller font and subscripts and the antecedent to the ellipsis is in bold:

In both of these sentences, the VP has been elided in the second half of the sentence. In both cases, the elided VP should be essentially identical to the antecedent in the first clause. That is, the missing VP in the first sentence can only mean wash the dishes, and in the second sentence, the missing VP can only mean wash the dishes on Tuesday. Assuming that the missing VP must be essentially identical to an antecedent VP leads to a problem, first noticed by Bouton (1970):

Since the elided VP must be essentially identical to its antecedent and assuming that the antecedent is a full VP, an infinite regress occurs, as indicated by the subscripted material, which would continue to repeat itself ad infinitum. That is, if we substitute in the antecedent VP into the position of the ellipsis, we must repeat the substitution process ad infinitum. The difficulty is illustrated further with the tree for the sentence:

The light grey font indicates the elided constituent, i.e. the ellipsis, and the underline marks the antecedent constituent to the ellipsis. Since the antecedent constituent contains the ellipsis itself, resolution of the ellipsis necessitates an infinite regress as the antecedent is substituted ad infinitum into the ellipsis cite. To avoid this problem, Sag (1976) proposed that the NP every book that Mary did undergoes quantifier raising (QR) to a position above the verb.

Now the reference for the elided VP is simply the following:

The analysis can now assume that the elided VP in the example corresponds to just read, since after QR, the antecedent VP no longer contains the object raised NP. The result is the following analysis:
