Natural Syntax is a developing deductive theory, a branch of Naturalness Theory. The naturalness judgements are couched in naturalness scales, which proceed from the basic parameters (or “axioms”) listed at the beginning of this paper. The predictions of the theory are calculated in the deductions, whose chief components are a pair of naturalness scales and the rules governing the alignment of corresponding naturalness values. Parallel and chiastic alignments are distinguished, in complementary distribution. Chiastic alignment is mandatory in deductions limited to unnatural environments. This paper exemplifies Natural Syntax using language data associated with reported speech in Standard English. Some of the deductions compare direc...
