  • Don't say NOO-kyuh-lur (as "uselessness" did), as if the word were spelled "nucular." This variant has long been "a much-derided aberration" (Richard Lederer), and current dictionaries, which rarely stigmatize pronunciations, call it "unacceptable" and "incorrect." Take care to say "nuclear" like "new" + "clear": N(Y)OO-klee-ur. -- The Orthoepist
