Definition of vigorous

The word "vigorous" has its roots in Latin. The Latin word "vigere" means "to be alive" or "to be in full strength," and it is also the source of the English word "vigor." The Latin phrase "vigor vivus" translates to "living strength" or "vital force." The English word "vigorous" entered the language in the 15th century, derived from the Old French word "vigeur", which was itself borrowed from the Latin "vigere". Initially, the word referred to physical strength, vitality, and energy. Over time, the meaning expanded to include mental or intellectual vigor, as well as the quality of being robust, healthy, and full of life. Today, "vigorous" is used to describe something that is strong, healthy, and full of energy, whether it be a person, an activity, or a process.
