subject properties are not tied to final subjects but can make reference to subjects at a distinct strata. Height conjecture In height conjecture analysis, a quirky subject gains the properties of an FP whenever it lands in the SPEC of that FP. To account for the QSH: TP is split into PerspP and BP T is split into 2 heads Persp then B; the former to bear PRO and the latter to bind to SOA The heads are marked [⋆nom⋆] (nominative DPs only), [⋆dep⋆] (dependant-case and nominative DPs), and [⋆d⋆] (any DP). A subject can pass through both [SPEC, Persp] and [SPEC, B], or only [SPEC, B] If the head B agrees with the QS, they merge. If B and the QS merge successfully, the same merging occurs if head Persp agrees with the QS. The raising of PRO to [SPEC, Persp] determines whether the quirky can occur in complement during control. This is according to the Perspectival Centre Constraint. If the quirky subject lands at [SPEC, Persp], it may be relativized on into a reduced relative clause. Other examples of quirky subjects In Icelandic, verbs can require a non-nominative subject. The following examples show an accusative subject and a dative subject, respectively. Quirky subjects can also occur when verbs taking a dative or genitive argument occur in the passive.
