  1. That will help you master the pronunciation. It’s the pronunciation of the second syllable that is in dispute.
    • The most widely accepted correct pronunciation of the word is “NEW-clee-er.” In this case (somewhat unusually), the word is spelled exactly how you are supposed to say it. Put the pronunciation on the first syllable. The "er" is pronounced like the "u" in the word "fur."
    • The pronunciation “NEW-clee-er” is widely regarded by experts as the “correct” pronunciation, even though another variant has been used so much by prominent people that, to some, it’s become another acceptable usage. [1]

  1. Some people, including some very prominent people, incorrectly say “nuke-you-lerr” or “Nu-cu-lar.” [2]
    • The mispronunciation of nuclear is so common that it’s found its way into popular culture. In the 1989 Woody Allen film “Crimes and Misdemeanors," Mia Farrow’s character says she would not fall in love with a man who pronounced the word “nucular." Another version of this is “NOO-kyuh-lur.” [3]
    • President George W. Bush, Dwight D. Eisenhower and Bill Clinton have pronounced the word this way in the past. President Jimmy Carter said “newkeeuh.” [4] Homer Simpson still says “nucular.”
  2. American dictionaries now recognize “NOO-kyuh-luhr” as an accepted variant of the word. That’s not the end of the story, though.
    • When a usage panel was convened by Harper Dictionary, members rejected this pronunciation 99 to 1. [5]
    • People might be confusing the word with words like “circular” and “secular.” At least one book attempted to argue the presidential versions were actually correct and that weapons labs since WW2 used the “nucular” pronunciation. It’s not a settled issue, though, so if you want to be safe, say, “NEW-clee-er.” [6]

    Expert Answer
    I totally understand how some words like "nuclear" can be tough to pronounce, especially if you have speech difficulties. Breaking it into syllables can help — try saying "nu" and "clear" separately, then combine them. Clapping out the syllables helps, too. If stuttering is a problem, take a deep breath first and go slower when you say it. Reducing pressure on your mouth parts, like where your tongue meets the roof, is good, too. Be patient with yourself, and keep practicing. It's fine to get help from a coach or use pronunciation tools. With time and the right strategies, you'll get there.
  • Question
    So, I can really say this word either way?
    Community Answer
    Well, you risk more people thinking you are wrong if you say "nucular," and they might laugh at you. So, if you want to err on the side of caution, say "NEW-clee-er" and no one can argue the point.
  • Question
    Why are you attempting to justify the obvious mispronunciation of the word nuclear?
    Community Answer
    Language changes. There is no "right" way, only more common/less common usages. Some usages carry class connotations.
