nuclear-powered

The compound adjective "nuclear-powered" is a modern construction from the mid-20th century, directly reflecting the technological advancement it describes. Its first element, "nuclear," derives from the Latin nucleus, meaning the kernel or central part of something, which in scientific terminology came to denote the core of an atom. The second element, "power," originates from the Latin verb posse (to be able), evolving through Old French to signify force, energy, or the capacity for action. The suffix "-ed" is added to the noun "power" to create an adjectival form meaning "equipped with." Thus, the word's literal logic is "provided with energy from the atomic nucleus," a meaning that remains transparently connected to its components.
