Yu, Chong-Taek. 1997. The Missing Features of Alternants after Spell-Out. Linguistics, 5-2, 1-19. An alternant of for with FF, PF and SF (= full features) Φ (forFPSF) assigns governed Case (GC) to PRO and a lexical infinitive subject before Spell-Out (S-O). The missing SF of for and both missing SF and PF of D(f,rFPSF) vanish like bubbles after S-0, meeting the condition of inclusiveness. An alternant of a PL to Φ (toFPSF) misses SF and PF after S-0, and an alternant of a complementizer (comp.) that Φ(thatFPSF) does so. The missing features disappear without leaving any traces. It seems that all the lexical items and alternants never miss their FF in the computational system. (Chonbuk Sanup University)
