Antecedent-Contained Deletion¶
Resolve a verb-phrase ellipsis whose surface host lies inside the constituent that appears to antecede it, forcing a syntax–semantics analysis that breaks apparent self-containment while preserving ellipsis identity and scope readings.
Core Idea¶
Antecedent-Contained Deletion, or ACD, is a configuration of verb-phrase ellipsis in which the ellipsis site appears at surface structure inside a phrase that is itself contained in the apparent antecedent VP. In I read every book that Mary did, the auxiliary did supports an elided expression interpreted roughly as read, yet it occurs inside the relative clause modifying the object every book that Mary did; that object is inside the larger VP read every book that Mary did. Copying the full apparent VP into the ellipsis site would reproduce the containing phrase and trigger infinite regress. Syrett's handbook review identifies this containment puzzle, its quantificational structure, and its experimental scope evidence.
Scope of Application¶
ACD is literal when a predicate ellipsis site is surface-contained in the phrase forming part of its apparent antecedent and interpretation requires a principled escape from self-containment.
- Formal syntax. Testing covert movement, constituency, and locality.
- Formal semantics. Building compositional interpretations without circular copying.
- Ellipsis theory. Refining syntactic, semantic, and discourse identity conditions.
- Quantifier scope. Using available readings to constrain QR height or alternatives.
- Relative-clause structure. Locating the ellipsis host inside the quantified DP.
- Language acquisition. Testing children's access to lower and higher readings.
- Sentence processing. Comparing online cost and antecedent preferences.
- Cross-linguistic research. Establishing language-specific ellipsis and quantification prerequisites before analogy.
Clarity¶
A clear ACD analysis displays the sentence, marks the elided material, brackets the containing DP or phrase, identifies every candidate antecedent, and states the identity and scope assumptions. If QR is proposed, the landing position and lower copy or trace are represented, and the analysis shows exactly why the selected antecedent no longer contains the ellipsis. If a variable-free or direct-compositional account is proposed, the semantic type and composition that avoid self-application are stated.
Manages Complexity¶
ACD compresses a large theoretical issue into a sharp diagnostic configuration. The apparent cycle forces a theory to coordinate constituency, ellipsis identity, quantifier scope, and semantic composition. It reveals hidden consequences of seemingly simple copying accounts and provides scope evidence where covert structure is otherwise difficult to observe. Complexity returns because judgments vary, multiple analyses can generate the same reading, and experimental processing effects need not directly reveal grammatical representation.
Abstract Reasoning¶
- Locate the overt ellipsis licensor and determine the category of missing material. 2. Identify the phrase that syntactically contains the ellipsis site. 3. Identify the VP or predicate constituent proposed as antecedent. 4. Test whether the containing phrase is itself inside that antecedent at surface structure. 5. Demonstrate the regress or identity failure produced by naive full copying. 6. List available lower and higher antecedents and the corresponding interpretations.
Knowledge Transfer¶
ACD transfers a general self-containment diagnostic: when an item depends on a representation that appears to contain that same item, naive substitution is unstable, so one must change the dependency domain, factor the representation, or alter semantic type. Similar reasoning appears in recursive definitions, macro expansion, cyclic dataflow, and anaphora. The linguistic accent is indispensable: ellipsis licensing, DP structure, quantifier scope, and compositional interpretation decide whether the apparent cycle is real and how it is resolved.
