A long-standing problem in analyzing Bantu verbal reduplication is to account for why tone does not usually transfer along with the segmental content of the Base. Even though most current theories of reduplication predict the reduplicant's tone (and other prosodic information) should be faithful to the Base, in fact, this is found in only one Bantu language, Chichewa. In other Bantu languages, either tone is realized only on the Base, or the reduplicant (RED) forms a single domain of tone realization with the Base. In this paper, I propose that tone realization in the RED+Base complex falls out if the complex is a compound verb stem. Then tone realization in the complex can be seen to be parallel to accent realization in compounds in other languages. I show this analysis improves on previous ones as it correctly predicts a three-way, rather than two-way, pattern of variation in realizing tone in reduplicated forms. The analysis thus confirms work showing that both morphological and phonological factors determine the realization of reduplicative morphemes.
