In plain English: Healthy means being in good physical and mental condition without any sickness or injury.

Usage: Use healthy to describe a person or animal that is physically fit and free from illness. Avoid using it metaphorically to mean morally upright or safe, as those nuances belong to words like wholesome or secure.
The word healthy is formed by adding the suffix -y to health. It entered English as a direct modification of an existing noun rather than evolving from a different root or meaning.
