What does vigorous mean?
Vigorous describes something that is strong, energetic, and forceful. The word is especially common in references to physical activity, where vigorous exercise means energetic exercise that places demands on the body. It can also characterize growth, defense, debate, or other activity that is intense and robust rather than weak or hesitant. In arguments and formal discussion, vigorous may describe forceful advocacy or criticism, sometimes suggesting that the manner of expression is energetic to the point of being forceful. Its positive connotation often centers on vitality and effectiveness, although context can make the word sound more critical when it describes aggressive or heated behavior. Vigorous is useful because it combines ideas of strength with sustained energy, making it more specific than merely saying that something is strong.
