energize

the word energize is a modern english formation built upon the noun energy. energy itself entered english in the 16th century from middle french 'energie', which derived from late latin 'energia', a term borrowed directly from greek 'energeia'. in greek, 'energeia' was a philosophical term coined by aristotle from 'en-' (in, at) and 'ergon' (work, activity), thus meaning 'activity' or 'being at work'. the verb-forming suffix -ize, of greek origin via latin and french, was productively attached to nouns to create verbs meaning 'to make or cause to be'. therefore, energize literally means 'to make full of energy' or 'to put into activity', a meaning that seamlessly bridges its ancient components to its modern applications in both physiological and mechanical contexts.

Structure: energ (energy) + ize (verb-forming suffix) energ (from greek 'energeia', meaning activity, operation, via latin and french; the noun 'energy' in english) + ize (verb-forming suffix from greek '-izein', via latin '-izare' and french '-iser', indicating 'to make or become').
