It is one thing to adopt the grammatical labels to categorize words in English sentence;it is quite another thing to go on to claim that the structure of English sentences should be like the structure of sentences in Latin.That was an approach taken by a number of influential grammarians,
mainly in eighteenth-century England,who set out rules for the "proper"use of English.This view of
grammar as a set of rules for the "proper"use of a language is still to be found today and may be best characterized as the prescriptive approach.Some familiar examples of prescriptive rules for English sentences are:
You must not split an infinitive.
You must not end a sentence with a preposition.
