This paper presents a case of parasitic tone harmony from Dioula d'Odienné in which super additivity (i.e., super cumulativity) of local and long-distance segmental feature similarities increases the likelihood of tone harmony. The analysis is couched in an agreement by surface correspondence framework (ABC), which formalises the widespread observation that more similar objects are more likely to interact. Super cumulativity in Dioula is formally captured by integrating weighted constraint conjunction into Maximum Entropy Harmonic Grammar. Counter to previous arguments that a weighted account of Optimality Theory does not need constraint conjunction, information-theoretic model comparison shows that weighted constraint conjunction improves the explanatory power of the grammar.
