   4# Syntax Universals from ConfigDim — Tier C Linguistics
   5
   6Chomsky's universal grammar proposes innate syntactic principles.
   7In RS terms, syntactic categories are forced by configDim D = 5.
   8
   9The five core phrase structure categories (NP, VP, AP, PP, AdvP) = configDim D = 5.
  10
  11These correspond to the 5-dimensional recognition taxonomy of the D=3 lattice.
