The nature of the interface between phonology and morphology has long been a matter of intense debate. One area that has received increased attention in recent years concerns a class of allomorphy called phonologically conditioned suppletive allomorphy (PCSA). This article offers two case studies of PCSA, one from Tiene, a Bantu language, and another from Katu, a Mon-Khmer language. The PCSAs in these languages are unique in that they both involve infixation. Our investigation suggests that a strictly input-driven subcategorization-based approach to PCSA does not offer a satisfactory account of this class of PCSA. Global optimization, which crucially references the well-formedness of output structures, is needed in allomorph selection to complement the often limited selectional power of subcategorization restrictions.
