The Aspectual Morpheme as and Feature Movement in Argument Small = Clauses In this paper I deal with the syntactic and semantic nature of the = particle as in English small clauses (SC) within Chomsky's (1995) = Minimalist Program, claiming that it generates as head of a hypothetical = aspectual phrase. The use of this functional head can be seen in the = following sentence: (1) I consider [Peter as intelligent]. Aarts (1992) classifies this element as part of Inflection. I will = follow this proposal, but after Pollock's (1989) splitting of INF into = different functional categories it needs some refinement and reviewing. = In the line of Ouhalla (1991), I will assume that INF is divided into = Tense and Aspect. My proposal is that SC particles are free aspectual = morphemes which generate as head of an Aspect Phrase with which the = entire SC (in the sense of Stowell, 1983) merges. In the spirit of = Cinque (1999), if a construction contains an aspectual particle, its = derivation should include the functional category ASP under which this = element is sheltered. The role of lexical aspect (aktionsart) in the selection of the SC = predicate and the generation of the intervening particles in ASP will = provide an optimal derivation for the constructions under study. = Sentences in (2-3) can illustrate my main argument. (2) a. I consider Mary interesting. b. I consider Mary interested in Linguistics. (3) a. I consider Mary as interesting. b. *I consider Mary as interested in Linguistics. Predicates are assigned an aspectual feature in the Lexicon. Following = Demonte's (1991) terminology, predicates are marked with the features [- = perfective] or [+ perfective], depending on whether they express a = permanent or transient property respectively. Both types can occur = within an SC, as it is shown in (2a-b), but if a particle like as = intervenes only [- perf] predicates are acceptable --compare sentences = (3a) and (3b)--. This leads me to conclude that as is an aspectual = element which is generated under ASP and is intrinsically marked with = the feature [- perf]. The aspectual feature of the SC predicate will = raise covertly to adjoin to the SC ASP and it is checked at Logical = Form, but if there is a mismatch of these features the derivation = crashes. This is the case of (3b). The process of feature checking in = the derivation of an SC containing as will have the representation in = (4): (4) [AspP DP Subject1 [ASP' [ASP FF of X-as] [XP t1 [X' X]]]] where X stands for any category in the role of predicate and FF for the = formal features of X, the aspectual value among them. Basically we have = two movements in this derivation. First, taking into account the bare = output conditions, the SC subject raises overtly to Spec of ASP to check = its nominal features, although its Case feature waits until Logical Form = to be checked at the matrix clause. Then, because ASP is weak in = English, the formal features of the SC predicate move to adjoin to the = ASP head after Spell-Out. It is just a feature movement If the aspectual = features of both X and ASP match the derivation converges; otherwise it = crashes, accounting for the contrast in (3). The importance of lexical aspect in the selection of SCs has been = previously suggested by Kitagawa's (1985) difference between state of = affairs and change of state predicates or by Raposo & Uriagereka's = (1995) distinction between individual-level and stage-level predicates, = but no mention of aspectual particles and their relevance in the optimal = derivation of SCs has been made before.
