Another way to understand the difference in concerns between systemic functional grammar and most variants of generative grammar is through Chomsky's claim that linguistics is a sub-branch of psychology . Halliday investigates linguistics more as a sub-branch of sociology.or Halliday, grammar is described as systems not as rules, on the basis that every grammatical structure involves a choice from a describable set of options. Language is thus a meaning potential. Grammarians in SF tradition use system networks to map the available options in a language.
