Cross-level Correspondence in Q Theory

Abstract

This paper examines cross-level interactions in basic systems modeling segmental harmony in Q theory (Shih & Inkelas 2019, S&I; see also Inkelas & Shih 2015, 2017). Q theory is a theory of segmental representations that decomposes segments (Qs) into linear strings of subsegments (qs). The component qs can differ in feature values, resulting in Qs with contour tones. S&I present Q theory as an alternative to autosegmental representations and use Agreement-by-correspondence (ABC; Rose & Walker 2004, Hansson 2010, Bennett 2015) analyses to derive various kinds of harmony and dissimilation patterns, particularly those involving tones. This paper shows that while the Q theory typologies share the characteristic structures of ABC(D) systems (Bennett & DelBusso 2018, DelBusso & Bennett to appear) at both q and Q levels, these (sets of) properties interact in more complex embedded structures.
