adj.
[From nucleus.] Usage Note: The pronunciation (nōō'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. |

nuclear
1846, "of or like the nucleus of a cell," from nucleus (q.v.), probably by influence of Fr. nucléaire. Use in atomic physics is from 1914; of weapons, from 1945. Hence nuclear physics (1933), nuclear energy (1941), nuclear war (1954). Nuclear winter coined by Richard Turco, but first attested in article by Carl Sagan in "Parade" magazine, Oct. 30, 1983. General sense of "central" is from 1912. Nuclear family, originally a sociologists' term, is first attested 1949 in "Social Structure," by American anthropologist G.P. Murdock (1897–1985).
