what are the major difference between modren linguists and the traditional grammarians in the study of a langauge? answer to the point
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.
