“ THIRD DEFINITION:—"An Adjective is a word added to a substantive, to express its quality."—Lowth, Murray, Bullions, Pond, and others. Here we have the choice of two meanings; but neither of them is according to truth. It seems doubtful whether "its quality" is the adjective's quality, or the substantive's; but in either sense, the phrase is false; for an adjective is added to a noun, not to express any quality either of the adjective or of the noun, but to express some quality of the thing signified by the noun. ”
