solar-powered

the term 'solar-powered' is a modern compound adjective, logically constructed from its constituent morphemes. 'solar' originates from the latin 'sol', meaning 'sun', entering english via the latin adjective 'solaris'. 'power' derives from the anglo-french 'poer', rooted in the latin verb 'posse' ('to be able'), and evolved to mean a source of energy or force. the suffix '-ed' is added to the noun 'power' to form a participial adjective, creating a term that literally means 'provided with or driven by the power of the sun', perfectly describing technology that converts sunlight into usable energy.

Structure: solar (sun) + power (energy) + ed (adjective suffix) solar (from latin 'solaris', meaning 'of the sun', adjective-forming suffix); power (from anglo-french 'poer', old french 'povoir', meaning 'ability, strength', noun); ed (from old english '-ede', '-od', past participle/ adjective-forming suffix)
