Thus, grammars that employ phrase structure rules are "constituency grammars" (= phrase structure grammars), as opposed to "dependency grammars", which view sentence structure as "dependency-based". What this means is that for phrase structure rules to be applicable at all, one has to pursue a constituency-based understanding of sentence structure. The constituency relation is a
