Language is conventional, and not only invented, but, in its progressive advancement, varied for purposes of practical convenience. Hence it assumes any and every form which those who make use of it choose to give it. We are, therefore, as rational and practical grammarians, compelled to submit to the necessity of the case; to take the language as it is, and not as it should be, and bow to custom.
PHILOSOPHICAL GRAMMAR investigates and develops the principles of language, as founded in the nature of things and the original laws of thought. It also discusses the grounds of the classification of words, and explains those procedures which practical grammar lays down for our observance.
PRACTICAL GRAMMAR adopts the most convenient classification of the words of a language, lays down a system of definitions and rules, founded on scientific principles and good usage, illustrates their nature and design, and enforces their application.
PRINCIPLE. A principle in grammar is a peculiar construction of the language, sanctioned by good usage.
DEFINITION. A definition in grammar is a principle of language expressed in a definite form.
RULE. A rule describes the peculiar construction or circumstantial relation of words, which custom has established for our observance.
ENGLISH GRAMMAR.
ENGLISH GRAMMAR is the art of speaking and writing the English language with propriety.
GRAMMAR teaches us how to use words in a proper manner. The most important use of that faculty called speech, is, to convey our thoughts to others. If, therefore, we have a store of words, and even know what they signify, they will be of no real use to us unless we can also apply them to practice, and make them answer the purposes for which they were invented. Grammar, well understood, enables us to express our thoughts fully and clearly; and, consequently, in a manner which will defy the ingenuity of man to give our words any other meaning than that which we ourselves intend them to express. To be able to speak and write our vernacular tongue with accuracy and elegance, is, certainly, a consideration of the highest moment.
