The question was about the differences in the new grammar vs. the traditional grammar. The answer does not address that question at all. In "traditional" grammar sentences were "parsed"; that is, they were divided into "parts of speech"-- subject, predicate, adjectives, adverb, etc. Modern grammar since Noah Chomsky has used a "tree" metaphor, in which each subject--predicate pair, called an "utterance" or a speech act," which "branch out" into "dependent (hanging) clauses." The emphasis now is the intention of the utterance, the communication function.

It extends to sociology and, of course, to philosophy, which has been prominent in the weighing of words for more than two thousand years and all these now in the nexus of mathematics strengthened by immense computer power. Modern Linguistics has horizons that were invisible to the phoneticians and grammarians of a hundred years ago; its present corpus is far beyond the compass of any individual scholar, and growing by the day. Graduates in Linguistics legitimately class themselves as scientists. The Cambridge Paperback Encyclopaedia, whose editor is a prominent professor of the subject describes Linguistics as The scientific study of Language. So no surprise that confidence in their discipline gives many of them assurance of being better fitted to pronounce on language than even consummate users of it. Here is that belief stated authoritatively by Laurie Bauer and Peter Trudgill, editors of the book
