A nasal consonant (NC) sequence, in most languages, will trigger a range of repair mechanisms because it is considered marked phonetically. Rule based theoretical models that account for *NC effects focus on how phonological rules condition morphological structures. This means that linguistic incursion in the role played by syllable phonotactics in the simultaneity of some processes is given minimal prominence. In this regard, Optimality Theory offers a better model because it licenses the multiplicity of the phonological processes through its principle of global constraint interaction. Studies of *NC effects have shown that there are similarities and differences in how languages resolve NC sequences. This paper argues that through constraint interaction, phonological processes used to resolve NC patterns in Olumarama can be adequately described. The analysis of data from Olumarama confirms that the language has its own rich set of constraints that determines repair mechanisms for the marked NC sequence.
