(from “The Fall of the House of Usher,” by Edgar Allan Poe) Although, as boys, we had been even intimate associates, yet I really knew little of my friend. His reserve had been always excessive and habitual. I was aware, however, that his very ancient family had been noted, time out of mind, for a peculiar sensibility of temperament, displaying itself, through long ages, in many works of exalted art, and manifested, of late, in repeated deeds of munificent [definition: very generous] yet unobtrusive charity, as well as in a passionate devotion to the intricacies [DEFINITION: many parts and complexities], perhaps even more than to the orthodox and easily recognizable beauties, of musical science. I had learned, too, the very remarkable fact, that the stem of the Usher race, all time-honored as it was, had put forth, at no period, any enduring branch; in other words, that the entire family lay in the direct line of descent [ROLLOVER; the Ushers had never married out of the Usher family], and had always, with very trifling and very temporary variation, so lain. It was this deficiency, I considered, while running over in thought the perfect keeping of the character of the premises with the accredited character of the people, and while speculating upon the possible influence which the one, in the long lapse of centuries, might have exercised upon the other—it was this deficiency, perhaps, of collateral issue, and the consequent undeviating transmission, from sire to son, of the patrimony with the name, which had, at length, so identified the two as to merge the original title of the estate in the quaint and equivocal appellation of the “House of Usher”—an appellation [definition: title or name] which seemed to include, in the minds of the peasantry who used it, both the family and the family mansion.
