"Convicted felon," "rural countryside" and "frozen tundra" are just some of the unnecessary word pairs cited in Richard Kallan's new book "Armed Gunmen, True Facts, and other Ridiculous Nonsense: A Compiled Compendium of Repetitive Redundancies" (Pantheon, 160 pages, $14.95). Kallan's hundreds of examples include "disappear from view," "weave in and out," "personal friend," "monetary fine," "royal prince" ("snooty foe of the proletariat prince," Kallan quips), "raining outside" ("less surprising than when it rains inside," says Kallan), and, of course, "fall down."
