Final answer:
To bring something back to life or renew its energy is to revitalize. Rain can revitalize an area affected by drought, similar to how caring and patient nurturing can revitalize a weakened person back to health.
Step-by-step explanation:
To bring something back to life, or to inject new energy in it, is to revitalize. A few days of rain can revitalize an area that's been suffering a mild drought. The process of revitalization can restore vitality and energy to something that has been weakened. The word suggests not only the act of bringing back to life, but also the idea of infusing something with new life and energy, making it robust and vigorous once more.
