nu·cle·ar

(no͞o′klē-ər, nyo͞o′-)

adj.

1. Biology Of, relating to, or forming a nucleus of a cell: a nuclear membrane.

2. Physics

a. Of or relating to atomic nuclei: a nuclear chain reaction.

b. Using or derived from the energy of atomic nuclei: nuclear power.

3. Of, using, or possessing atomic or hydrogen bombs: nuclear war; nuclear nations.

4. Drastic or extreme; radical: "The Senate majority leader ... had vowed to invoke what some have called the nuclear option to do away with judicial filibusters" (Carl Hulse).

[From nucleus.]

Usage Note: The pronunciation (no͞o′kyə-lər), which is generally considered incorrect, is an example of how a familiar phonological pattern can influence an unfamiliar one. The usual pronunciation of the final two syllables of this word is (-klē-ər), but this sequence of sounds is rare in English. Much more common is the similar sequence (-kyə-lər), which occurs in words like particular, circular, spectacular, and in many scientific words like molecular, ocular, and vascular. Adjusted to fit into this familiar pattern, the (-kyə-lər) pronunciation is often heard in high places. It is not uncommon in the military in association with nuclear weaponry, and it has been observed in the speech of US presidents, including Dwight D. Eisenhower and George W. Bush. The prominence of these speakers, however, has done little to brighten the appeal of (no͞o′kyə-lər), which was considered acceptable to only 10 percent of the Usage Panel in our 2004 survey.

nuclear

(ˈnjuːklɪə)

nu•cle•ar

(ˈnu kli ər, ˈnyu-; by metathesis -kyə lər)

adj.

1. pertaining to or involving atomic weapons.

2. powered by atomic energy.

3. having atomic weapons: a nuclear submarine.

4. of or forming a nucleus: nuclear particles.

[1840–50; compare French nucléaire]

pron: The second and third syllables of nu•cle•ar are commonly pronounced as (-kli ər) which can be transcribed more broadly as (-klə yər) The somewhat controversial pronunciation of these two syllables as (-kyə lər) prominent in recent years, results from a process of metathesis in which the sounds (l) and (y) change places. This pronunciation, reinforced by analogy with words like molecular, is disapproved of by many, although it occurs among such highly educated speakers as scientists, professors, and government officials.

nu·cle·ar

(no͞o′klē-ər)

1. Relating to or forming a cell nucleus.

2. Relating to atomic nuclei.

3. Using energy derived from the nuclei of atoms: a nuclear power plant.

Usage The words nuclear and atomic mean the same thing when referring to weapons or to the making of power: We say nuclear (or atomic) weapons and nuclear (or atomic) energy. But in most scientific uses nuclear and atomic mean different things. Nuclear is used to refer to the nucleus of an atom, where the protons and neutrons are located. When a radioactive element gives off a neutron, for example, we call this a nuclear event. Atomic, by contrast, is used to refer to the outer layers of the atom, where the electrons that orbit about the nucleus are located. So when two or more atoms share electrons to form a covalent bond, we call this an atomic interaction.
