Pronunciation: [njˈuːkli͡ə] (IPA) 
The word "nuclear" is often misspelled as "nucular", likely due to its pronunciation. The correct way to spell this word is "nuclear", with three syllables: /ˈnuː.kli.ər/. The first syllable is pronounced like "new" (/nuː/), the second syllable is pronounced like "klee" (/kli/), and the final syllable is pronounced like "uh" (/ər/). It is important to use the correct spelling to avoid confusion and improve communication skills.
Nuclear, as an adjective, refers to something related to or involving atomic nuclei or nuclear energy. It pertains to the fundamental particles and forces that constitute the nucleus of atoms, as well as the reactions and processes associated with them.
Nuclear can specifically describe the utilization of atomic energy, typically obtained through the process of nuclear fission or fusion, for various purposes. This includes the generation of electricity by nuclear power plants, where the controlled splitting of radioactive atoms produces heat that is converted into usable energy. Alternatively, nuclear energy can be used for weaponry purposes such as nuclear bombs or missiles, which rely on the immense release of energy resulting from the uncontrolled explosion of atomic nuclei.
Furthermore, the term nuclear can refer to phenomena or materials that exhibit innate radioactivity due to the unstable nature of their atomic nuclei. For instance, radioactive substances emit alpha, beta, or gamma radiation as a consequence of nuclear decay, in which atomic nuclei undergo spontaneous changes to achieve greater stability. This can have significant implications for fields like medicine, where nuclear medicine employs radioactive isotopes for diagnostic or therapeutic purposes.
Overall, the term nuclear encompasses the scientific study, harnessing, and potential hazards associated with atomic nuclei, their reactions, and their radioactive properties.

The word "nuclear" comes from the Latin word "nucleus", meaning "kernel" or "core". Its use in English originated in the early 20th century, specifically in the field of physics, to describe the atomic nucleus, which is the dense core at the center of an atom. As nuclear energy and the study of atomic physics developed, the term "nuclear" became widely used to refer to anything related to atomic nuclei or the energy released from them.
