Morphology

nuclear = nucleus (transparent) = nucleus + ar

Derived from 'nucleus' meaning the central part of an atom; the adjective directly denotes relation to atomic nuclei and related energy.

Etymology

Nuclear comes from the Latin word nucleus, which meant 'little nut' or 'kernel', giving the idea of a very small but powerful core. So nuclear in physics and energy means 'of the atom's core', the place where huge power can be held or released for power or weapons.
