-ousone who does, agent
=vigorous

vigor + -ous ('full of') = 'full of energy.' Note: vigor comes from Latin vigēre ('to be lively/strong'), a cousin of vīvere rather than the same root — same life-force feel, different family. It applies both to bodies (a vigorous young athlete) and to actions (a vigorous defense).
