Add to ORKGThe process of Merge is governed by an opacity condition that restricts its access to terminal and nonterminal nodes in the geometry of phonological features. This restriction upon accessibility of the phonological process contributes to a unification of the three sub-principles of Full Interpretation that Takahashi (2004b) formulated. The net effect of the principle of Sonority Sequencing Generalization (SSG) is derivable directly from assumptions on Merge, fed by Erase. The function of the principle of Obligatory Contour Principle (OCP) is properly included in that of SSG, which implies that the former is an effect derivable from the latter. The linguistic data covered by the two phonological principles, SSG and OCP, are accounted for by ...
