Late Middle English is a VO language in which surface OV order can nev
ertheless be found. This has been taken to show that the language has
both OV and VO as possible underlying orders. However, there are vario
us types of data that this hypothesis cannot account for. It is theref
ore argued in this article that late Middle English only had VO order
underlyingly, and that all surface OV orders are derived by means of l
eftward movement of the object across the verb, in a manner fully comp
atible with the Minimalist Program. In surface OV, the object moves ov
ertly to the functional projection AgrOP for feature-checking; LF move
ment is also possible (yielding surface VO), since the two derivations
are equally economical. Pronominal objects can move to a higher cliti
c position. This analysis is shown to account for a wide range of data
.
