5.3 Rizzi’s (2006) Subject Criterion<br />

As we know, <strong>the</strong> Extended Projection Principle (EPP) <strong>of</strong> <strong>the</strong> GB framework expresses <strong>the</strong><br />

obligatoriness <strong>of</strong> a subject position in <strong>the</strong> sentence. Within <strong>the</strong> GB ap<strong>pro</strong>ach, <strong>the</strong> EPP position<br />

is filled after <strong>the</strong> raising <strong>of</strong> an argument from its <strong>the</strong>matic position. The EPP position is taken<br />

to be an A-position <strong>and</strong>, as such, a final target <strong>of</strong> movement. Since under Minimalist tenets<br />

move α is constrained by scope <strong>and</strong> feature-checking requirements (cf. Chomsky 2005),<br />

Nominative Case assignment is <strong>of</strong>ten <strong>of</strong>fered as morphological motivation for subject<br />

movement.<br />

However, as suggested in Rizzi (2006), at least partial dissociation between <strong>the</strong> EPP<br />

position <strong>and</strong> <strong>the</strong> Case-Agreement system should be assumed. Evidence is given by <strong>the</strong><br />

existence <strong>of</strong> quirky (non-nominative) subjects, with <strong>the</strong> preverbal subject position filled by an<br />

inherently Case-marked phrase <strong>and</strong> agreement construed with an internal argument:<br />

(33) A Gianni piacciono queste idee<br />

to Gianni please.3PL <strong>the</strong>se ideas.NOM<br />

‘Gianni likes <strong>the</strong>se ideas.’<br />

As <strong>the</strong> element satisfying <strong>the</strong> EPP <strong>and</strong> <strong>the</strong> agreement element can be dissociated, Rizzi<br />

assumes two distinct heads, each related to a distinct DP position (according to <strong>the</strong> common<br />

assumption that a head cannot carry a complex feature specification, allowing it to enter an<br />

Agree relation with one phrase <strong>and</strong> at <strong>the</strong> same time attract ano<strong>the</strong>r phrase). This distinct<br />

subject position is postulated in a different zone <strong>of</strong> <strong>the</strong> IP space, so that <strong>the</strong> following<br />

hierarchy is <strong>pro</strong>posed (cf. also Cardinaletti 2004):<br />

(34) EPP…. Agr …. DP1…. DP2<br />

Given this ‘dissociation’, Rizzi explores <strong>the</strong> possibility that <strong>the</strong> EPP position is<br />

connected with a topic-related feature. However, he rejects <strong>the</strong> possibility <strong>of</strong> a complete<br />

assimilation between subject <strong>and</strong> topics because “subjects are possible in out <strong>of</strong> <strong>the</strong> blue<br />

contexts, while CLLD objects are not”. 47 To support this claim, he <strong>pro</strong>vides examples like<br />

(35):<br />

(35) a. Cosa è successo?<br />

‘What happened?’<br />

b. Un camion ha tamponato l’autobus per Roma<br />

a truck have.3SG bump.PAST <strong>the</strong> bus for Rome<br />

‘A truck has bumped into <strong>the</strong> bus for Rome.’<br />

c. #L’ autobus per Roma, un camion lo ha tamponato<br />

<strong>the</strong> bus for Rome a truck it have.3SG bump.PAST<br />

‘(as for) <strong>the</strong> bus for Rome, a truck has bumped into it.’<br />

Rizzi thus concludes that <strong>the</strong> EPP is a manifestation <strong>of</strong> a Subject Criterion: “<strong>Subjects</strong> occur in<br />

<strong>the</strong> higher part <strong>of</strong> <strong>the</strong> inflectional field, higher than Agr, or whatever head carries <strong>the</strong><br />

agreement features if independent agreement heads do not exist” (Rizzi 2006, p. 120).<br />

I suggest that Rizzi’s sentences in (35b-c) do not <strong>pro</strong>ve a ‘dissociation’ between <strong>Topics</strong><br />

<strong>and</strong> <strong>the</strong> EPP feature but, ra<strong>the</strong>r, that a weak <strong>pro</strong>noun in subject position is <strong>the</strong> best syntactic<br />

47 Rizzi (2006) argues that what makes a difference between subject <strong>and</strong> topic is <strong>the</strong> <strong>pro</strong>perty <strong>of</strong> being D-linked<br />

(cf. note 15), since “topics are always D-linked, while subjects not necessarily”. As already discussed in sections<br />

3.1-3.2, D-linking is not a <strong>pro</strong>perty <strong>of</strong> all types <strong>of</strong> Topic <strong>and</strong>, in particular, not a <strong>pro</strong>perty <strong>of</strong> <strong>the</strong> Aboutness-shift<br />

Topic.<br />
