Blurb:

Paster (2005) presents cases of syllable-counting suppletive allomorphy (SCA) which are not driven by phonological optimization, and argues for an account using morphological subcategorization frames. In this paper, I show that all relevant cases of non-optimizing SCA can be captured by generalizing a prosodic-templatic approach for truncation to allomorphy, implementing templates by indexed constraints (Pater 2007, 2009, Flack 2007) or by affixation of prosodic material (Bermúdez-Otero 2012, Kirchner 2010, 2013). Under this analysis, templatic effects in SCA and truncation are unified and the range of possible SCA effects is substantially restricted.
