reinvigorated

the word 'reinvigorated' is built upon the latin root 'vigor', meaning active strength or energy, which itself traces back to the proto-indo-european root weg- meaning 'to be strong or lively'. the latin prefix 'in-' was added to form 'invigorare', meaning 'to give strength to'. the english word then incorporates the iterative prefix 're-', denoting repetition. thus, the literal construction 'to-strengthen-into-again' evolved into the modern abstract sense of restoring vitality, energy, or enthusiasm to someone or something that had become tired or less active.

Structure: re (again) + in (in) + vigor (strength) + ated (adjective/verb suffix) re- (latin prefix, meaning 'again'); in- (latin prefix, meaning 'in, into'); vigor (latin root, meaning 'strength, energy'); -ated (latin-derived suffix, forming adjectives or past participles of verbs).
