Etymology

The word vital traces back to Latin vitalis, derived from vita (life). It originally described things pertaining to life or survival, later expanding to mean "energetic" (full of life) and "critically important" (as essential as life itself). The logical progression reflects how life-sustaining qualities metaphorically extend to vigor and significance.
