Pollock's Verb Movement Diagnostics #

@cite{pollock-1989}

Connects the Minimalist verb movement parameter (Theories/Syntax/Minimalism/Formal/HeadMovement/VerbMovement.lean) to the theory-neutral verb movement and do-support data in SubjectAuxInversion.lean.

Structure #

§1 Pollock diagnostics: Each of Pollock's 12 examples is paired with the theory's prediction via verbPrecedesDiagnostic. French examples (V raises) are grammatical when V precedes the diagnostic; English examples (V in situ) are ungrammatical in the same configuration.

§2 Do-support: Each do-support datum is paired with needsDoSupport. Lexical verb contexts that need do-support are grammatical when do-support is used and ungrammatical without it.

§3 Convergence: All four diagnostics agree for any parameter setting.

§4 Anticorrelation: Do-support and verb raising are complementary.

Each theorem pairs the datum's acceptability judgment with the verb movement theory's prediction. French examples have french (= .raises), English lexical verb examples have englishLexical (= .inSitu).

Each do-support datum is paired with needsDoSupport. Grammatical do-support examples confirm that English lexical verbs need it; ungrammatical examples confirm that auxiliaries do not.

All four diagnostics agree for any parameter setting. This is the core of Pollock's argument: the four tests are not independent observations but consequences of a single parameter (V-raises vs. V-in-situ).

Do-support and verb raising are complementary: a parameter setting that raises V never needs do-support, and a setting that keeps V in situ always needs it. This follows from the theory: do-support exists because V cannot raise.
