Regular Grammar, Lexical Grammar, Systematic Syntax, Uniform Syntax

for a decade, i wanted a term to describe certain syntax that's regular, such as a idealized lisp, XML, or Wolfram Language syntax.

I've used “regular grammar” and “lexical grammar”, but that's wrong. Perhaps systematic syntax or uniform syntax.

the Common Lispers, at times claim lisp syntax is simple by the idiotic phrase “no syntax”, at other times says lisp syntax can't described by grammar because of lisp reader. LOL
