Interacting tonal processes in Susu

Susu, like a number of other Mande languages, displays tonal melody neutralization in some nominal constructions. This paper illustrates that in addition to the lexical tonal melody of input elements playing a key role in the outcomes of neutralization, prosodic structure and interactions between multiple tonal processes are also important factors driving observed surface forms. We present novel data on a wide variety of compounds containing complex word shapes; tonal outcomes in such compounds offer a deeper look at factors influencing neutralization. We posit that tones in Susu nominal compounds are subject to Neutralization-by-Copy, which subsequently interacts with analogous, more generalized processes that further smooth the overall tonal contours of a given word.
