3 On the other hand, others have pointed out that preverbal subjects are
at least par- tially distinct from other topicalised constituents in
displaying residual properties characteristic of items in an A-position
(Horrocks 1994). Although there is a general consensus that inverted
orders as in (lb-c) arise when the verb occupies a slot higher than the
structural position hosting the subject, in the light of an articulated
INFL projection (see below), there is no agreement concerning the nature
of the head hosting the verb, the nature of the projection host- ing the
subject and whether or not an expletive is required. Greek has no
infinitives. All its moods (indicative, subjunctive, imperative) are
expressed by fmite forms throughout; specifically, the 'subjunctive'
mood consists of the particle na plus fully inflected forms of the verb,
being the common translational equivalent of the English infmitive. A
number of researchers have analysed na as a subjunctive marker
(Philippaki-Warburton & Veloudis 1984, Terzi 1992, Rivero 1994 among
others), while others have argued that it behaves like a complementizer
(Agouraki 1991, Tsoulas 1993). We will return to the properties of
na-clauses later on. (3) a. thelo na fIjis Subjunctive want-lsg subj

an indeclinable verbal form, the so-called gerund or active participle.
