Abstract Merge, a sole syntactic operation is attributed to the basic property. A syntactic element normally dominates another syntactic one uniquely. However, there exists another option of dominance, i.e. a syntactic element dominates more than two elements, called multidominance, which follows from three dimensionality. This paper argues that coordination, Partial Wh-questions, and Head Internal Relative Clauses can be analyzed using multidominance.
