The word "vigorous" stems from the Latin vigor (meaning "liveliness, energy"), derived from vigere ("to be lively or thrive"). The suffix -ous (from Latin -osus) denotes "full of" or "having the quality of." Thus, "vigorous" literally means "full of vigor" or "characterized by energy and strength." The term entered Middle English via Old French vigoros, retaining its core sense of vitality and force.
