Blurb:

system, grammar, typology are defined. The three key problems are stated:


(1) What defining characteristics must all Violation Tableaux (VT) representations of a typology share?


(2) When does a set of grammars constitute an OT typology?


(3) When does a subset of the grammars in a typology form a coherent class that can be described as a kind of super-grammar?


An order and equivalence structure on grammars, the ‘Mother of All Tableaux’ (MOAT), is introduced as a graphical structure similar to a Hasse diagram, and it is shown in broad strokes how it resolves these problems.
