Gouskova, Maria. 2007. The reduplicative template in Tonkawa. Phonology 24:3, pp. 367-396.
Generalized Template Theory holds that templatic restrictions on reduplicative morphemes follow from independent, general principles. Under lexically indexed constraint theory, however, reduplicants are in no way special—morpheme-specific constraints may apply just to reduplicants. This article presents reduplication patterns in Tonkawa, which are argued to require reduplicant-specific constraints. In Tonkawa, the reduplicant is limited in size to CV and is usually syllabified as a light syllable. Even though the language typically prefers heavy syllables word-initially, they are light if the syllable is a reduplicative prefix. This size restriction is backcopied onto the first syllable of the base. In the context of the prosodic phonology of Tonkawa, this pattern can only be understood if there is a reduplicant-specific prohibition against heavy syllables. This prohibition is formulated in terms of lexically indexed constraints on the reduplicant, which allows for a nuanced understanding of the emergent CV-template.
Tonkawa reduplication data (txt) I am making the data that I used for this paper available in a tab-delimited text file. Included in the file are all the forms I could find in Hoijer’s 1933 grammar that were unambiguously reduplicated.
