+==The core of the syntax==
+
+Among all categories and functions, there is is a handful of the 
+most important and distinct ones, of which the others are can be 
+seen as variations. The categories are
+```
+  Cl ; VP ; V2 ; NP ; CN ; Det ; AP ;
+```
+The functions are
+```
+  PredVP  : NP  -> VP -> Cl ;  -- predication
+  ComplV2 : V2  -> NP -> VP ;  -- complementization
+  DetCN   : Det -> CN -> NP ;  -- determination
+  ModCN   : AP  -> CN -> CN ;  -- modification

+This [toy Latin grammar  latin.gf] shows in a nutshell how these

+language. We will refer to the implementations contained in it

 So far we just give links to the implementations of each API.
