RT Journal Article SR Electronic(1) A1 Nevins, Andrew Ira YR 2005 T1 Microvariations in harmony and value-relativized parametrization JF Linguistic Variation Yearbook VO 5 IS 1 SP 119 OP 164 DO https://doi.org/10.1075/livy.5.05nev PB John Benjamins SN 1568-1483, AB This paper explores a parametric delimitation of the space of possible harmony patterns with respect to the class of feature-values that are visible. Extending the framework of Calabrese (1995), the proposal is that alternating morphemes that are searching for a harmonic value may have access toall-values, only asingle-value, or thecontrastivevalues of the harmonic feature. Two cases of microvariation are explored: [ATR] vowel harmony in Standard Yoruba vs. Ife Yoruba, which reduces to the setting of the relativization-value toallvs.contrastive, and vowel-consonant interactions mediated by [high] harmony in Sanjiazi Manchu vs. Sibe, which reduces to the parametric setting ofcontrastivevs.single-value., UL https://www.jbe-platform.com/content/journals/10.1075/livy.5.05nev
