vitality

This term describes a vibrant, pulsing energy that suggests more than just simple strength; it implies a capacity for growth, resilience, and an enduring spirit. It is frequently used to describe the peak of health in a person or the thriving nature of a community or ecosystem.

As an uncountable noun, it does not have a plural form and cannot be counted with numbers. To quantify it, one must use partitive phrases such as a sense of vitality or a burst of vitality.
