Good English and Bad English:There is also the difference between what we call good English and bad (or vulgar) English. By good English we mean those words and those meanings national of them and those ways of putting them together that are used generally by the best educated people of the present day; and bad English is, therefore, simply that which is not approved and accepted by good and careful speakers and writers. Then, again, we find that good English, when spoken, differs slightly from the language of well written books. In ordinary conversation we use, for instance, shortened forms of words, familiar expressions, and a loose arrangement of our sentences, which do not seem fitted for the higher kind of literature. We have in this Good English is reputable, recent, and way a classification of good English into standard literary English and standard spoken (or colloquial) English.
Etymology:The description and classification of the different words we use in speaking and writing. This is known as Etymology. The term properly means “a discussion of the true source of a word ; " but, by writers on language, its meaning has been extended to include the classification of words, the consideration of their changes of form, and the history of then- growth.
Syntax:An account of the ways in which words are properly combined to express our thoughts and feelings. This is known as Syntax; the term literally means "a putting together."
Phonetics:An account of the Sounds and Alphabet of the language—how our spoken words are correctly sounded, and how they are represented by letters. Strictly speaking, this subject does not form part of Grammar, which, as the term is now generally understood, consists of Etymology and Syntax; but, as it is of importance in connection with a discussion of the formation of words, some knowledge of it is necessary. In Grammar these divisions will not be kept quite separate, but will be taken up in parts when it seems best for the presentation of the subject.

It is constant practice, under never-failing watch and correction that makes Why English Grammar is a valuable study.
