To explain seemingly idiosyncratic restrictions on long passivization of causative/perception verbs in English and Brazilian Portuguese, we show that (a) long passives are blocked wherever the complement of a causative/perception verb constitutes a VoiceP/ProgP phase; (b) both TP complements and VP complements facilitate long passivization. To account for these patterns, we propose that A-movement can only cross a single phase head due to Chomsky’s (2001) (second) Phase Impenetrability Condition and cannot use phase-edge escape hatches, but that T’s EPP feature serves to feed A-movement into the matrix clause. In essence, successive-cyclic A-movement is possible only where embedded T is present to facilitate it.
