Lev Blumenfeld and Ida Toivonen’s article A featural paradox in Votic harmony has appeared in Natural Language and Linguistic Theory. The work that led to this fourteen-page article began in 1998. The paper is available here and the abstract follows.
In this paper we present a novel argument against strict locality in vowel harmony: a vowel’s feature may have a double identity, active in one process and neutral in another. Such is the behavior of [back] in Votic [i]. It is invisible to harmony, while simultaneously triggering an assimilation process. We argue that no feature-sharing account of this phenomenon is plausible, including the relatively powerful extension of Span Theory that permits vowels in a harmonic span to remain unassociated (and unharmonized) with the span’s head. We offer instead an account based on the Agreement-By-Correspondence approach to long-distance assimilation.
