Grammar, as an art, is the power of reading, writing, and speaking correctly. As an acquisition, it is the essential skill of scholarship. As a study, it is the practical science which teaches the right use of language.

An English Grammar is a book which professes to explain the nature and structure of the English language; and to show, on just authority, what is, and what is not, good English.

ENGLISH GRAMMAR, in itself, is the art of reading, writing, and speaking the English language correctly. It implies, in the adept, such knowledge as enables him to avoid improprieties of speech; to correct any errors that may occur in literary compositions; and to parse, or explain grammatically, whatsoever is rightly written.

To read is to perceive what is written or printed, so as to understand the words, and be able to utter them with their proper sounds.

To write is to express words and thoughts by letters, or characters, made with a pen or other instrument.

To speak is to utter words orally, in order that they may be heard and understood. Grammar, like every other liberal art, can be properly taught only by a regular analysis, or systematic elucidation, of its component parts or principles; and these parts or principles must be made known chiefly by means of definitions and examples, rules and exercises.
