Pronunciation: [nˈʌkjʊlə] (IPA) 
The word "nuclear" is often misspelled as "nucular". This is because the word ends with the letters "cle" which are pronounced as "kyool" in IPA (International Phonetic Alphabet). The sound "kyoo" can be confused with the sound "ku" which is spelled as "cular". However, the correct pronunciation of "nuclear" is "new-klee-er". It is important to use the correct spelling and pronunciation of words to effectively communicate with others.
The word "nucular" is commonly considered a mispronunciation and a colloquial variant of "nuclear". It does not have a separate etymology from the word it derives from.
The word "nuclear" dates back to the mid-19th century and is derived from the Latin word "nucleus", meaning "a small nut or kernel". "Nucleus" was later used in scientific contexts to refer to the central part of an atom, around which protons and neutrons are found. The term "nuclear" was initially associated with atomic physics and atomic energy.
The mispronunciation of "nuclear" as "nucular" has become fairly common in certain English-speaking communities, garnering attention due to its use by notable individuals, including some former U.S. presidents.
