This appendix is divided into two parts. First we provide a list of the modules given in Chapter 5 along with a description of the kinds of connections they can make and the grammatical constructions they allow. This list will be divided into four sections for heuristic purposes, and also to provide a method for testing the modules – the syntax crystal game. The second part describes additional grammatical constructions not mentioned in Chapter 5 but considered important for theories of grammar. We provide syntax crystal modules for these constructions and discuss how they can be handled.

It is important to point out that all the modules we describe are supposed to show only how the constructions can be handled by modules. We make no claim that grammatical constructions must be handled in exactly this manner. Our goal is only to show what the syntax crystal model can explain, how it can explain it, and occasionally, what it has difficulty explaining. We are saying: Given this sort of rule, with these sorts of properties, here are some of the constructions it can handle. We use English, as we have mentioned before, because it is a very complex and rich language. But we believe that the principles of the syntax crystal can be used to construct modules that will work for other languages.
