'nuclear-dependent' originates from the combination of 'nuclear,' derived from the Latin word 'nucleus,' meaning 'kernel' or 'core,' and 'dependent,' from the Latin 'dependere,' meaning 'to hang down from.'

'Nuclear' evolved from the Latin 'nucleus' through French 'nucléaire,' while 'dependent' evolved from Latin 'dependere' through Old French 'depondre.'

Initially, 'nuclear' referred to the core of an atom, but it evolved to include energy derived from nuclear reactions. 'Dependent' has maintained its meaning of reliance.
