Adjective Clauses.
375. As the office of an adjective is to modify, the only use of an adjective clause is to limit or describe some noun, or equivalent of a noun: consequently the adjective may modify any noun, or equivalent of a noun, in the sentence.
The adjective clause may be introduced by the relative pronouns who, which, that, but, as; sometimes by the conjunctions when, where, whither, whence, wherein, whereby, etc.
Frequently there is no connecting word, a relative pronoun being understood.
Examples of adjective clauses.
376. Adjective clauses may modify—
(1) The subject: "The themes it offers for contemplation are too vast for their capacities;" "Those who see the Englishman only in town, are apt to form an unfavorable opinion of his social character."
(2) The object: "From this piazza Ichabod entered the hall, which formed the center of the mansion."
(3) The complement: "The animal he bestrode was a broken-down plow-horse, that had outlived almost everything but his usefulness;" "It was such an apparition as is seldom to be met with in broad daylight."
(4) Other words: "He rode with short stirrups, which brought his knees nearly up to the pommel of the saddle;" "No whit anticipating the oblivion which awaited their names and feats, the champions advanced through the lists;" "Charity covereth a multitude of sins, in another sense than that in which it is said to do so in Scripture."
