vigor

Think of a young plant pushing through the soil. That image captures this idea well. It is not only physical strength, but also mental and emotional energy. A person with it meets life with enthusiasm and staying power. You might notice it in an athlete's movement or in the clear, lively thinking of a writer. After a long illness, someone may slowly regain it and begin to feel strong and active again.

The word suggests a healthy, active force, something that helps living things grow and do well. A garden full of life shows it; a weak, drooping plant does not. It means more than simply "not weak." It points to a strong supply of energy, drive, and life.

Vigor describes strong energy, vitality, or strength, whether physical, mental, or emotional. It is more than the simple ability to act. It suggests an active and eager force that supports growth, recovery, and effective action. For example, saying "Despite her age, she approached the challenge with remarkable vigor" means she faced it with real energy and determination, not just effort.

You can use the word for a person's physical stamina or mental sharpness, but it is not limited to people. A vigorous debate is lively and energetic. A vigorous economy grows strongly. A vigorous plant is healthy and thriving. In each case, the idea is the opposite of weakness, dullness, or inactivity.

Historically, "vigor" comes from the Latin verb vigere, which means "to be lively" or "to thrive." It is often contrasted with weakness, tiredness, or decline. In a medical context, a doctor might describe a patient's vigor as a sign of general health and recovery. Whether you are talking about a strong athlete, a growing business, or a resilient spirit, "vigor" points to an abundance of energy and the ability to act with strength and life. It is not just about being alive, but about being fully active and full of force.
