We argue that the phenomenon described and discussed in the literature as l
ocative or stylistic inversion in English is actually a conflation of two q
uite different constructions: on the one hand, light inversion (LI), in whi
ch the postverbal NP element can be phonologically and structurally extreme
ly simple, possibly consisting of a single name, and on the other hand heav
y inversion (HI), where the postverbal element is heavy in the sense of Hea
vy NP Shift.(1) We present evidence that the preverbal PP in LI patterns wi
th subjects but the PP in HI is a syntactic topic, using a variety of tests
which distinguish A-positions from (A) over bar -positions. Other signific
ant differences between HI and LI, such as the classes of verbs which suppo
rt these two constructions respectively, and the differential behavior of H
I and LI with respect to adverbial placement, provide support for interpret
ing HI as a case of Heavy NP Shift applying to subject constituents.
